Fatigue Test Optimization

Our unique combination of real world experience with fatigue analysis combined with analytical (FEA) methods can be leveraged in your company to reduce test equipment and time devoted to proving fatigue durability for each production run, or development samples.

FEA Software Sales

We offer and support the SIMULIA Abaqus FEA software suite which includes high level nonlinear Finite Element Analysis capability along with explicit dynamics for a complete multi-physics solution which has been developed into an elegantly simple environment through the development of Abaqus/CAE.  Fatigue analysis and product optimization software is also available and is often inclusive in the same package.

  • SIMULIA Abaqus (Structural analysis)
  • SIMULIA fe-safe (Fatigue)
  • SIMULIA Tosca (Optimization)

See the video below for an example of collaboratively using these tools.


For projects involving post-failure cases, we have done many precise analysis projects. We collaborate with test labs, partner Forensic Engineers and Metallurgists to study and resolve a wide array of failure related cases. This type of work will often involve fatigue analysis, which is one of our specialties. We can support you with the more common individual part failure investigation, or help you with a full system analysis.

Refining Big Ideas
With Cost-saving Simulations



Abaqus Software Performance

“We used Abaqus/CAE to develop a next generation of products for the oil & gas industry. The original design intent of the project was to use Abaqus as a tool to speed up validation cycles of manufactured components. In the process of developing a representative simulation we reduced required testing dramatically. The model simulation that was developed allowed us to fully understand a complex interaction of multiple parts acting in a specific sequence. This knowledge allowed us to come up with products that perform better than any other competitor in the same marketplace. In fact, the design enhancements resulted in the introduction of a new product line that does not exist in any similar form in the industry.

Abaqus Software Support

FEA SERVICES truly feels like a part of our team and we could not be happier with the cost and quality of service. Not only did FEA SERVICES approach us with a cost savings solution but did so in a timely manner with little to no changes on our end.”

Daniel Wilson – PLH ADVANCED ENGINEERING – Salt Lake City, UT


Abaqus Software Support

“I just want to thank the quick action of FEA SERVICES and Simulia regarding our issue yesterday. We had an internal situation that completely removed our license server from our system, and your team was excellent in responding quickly and getting us back up and running. It was amazing and speaks well of your company and the systems you have in place. We are a very happy customer and would refer you to anyone in need of your software services.”

James Thomason – McMILLEN JACOBS ASSOCIATES – San Francisco, CA


Thermal Mechanical Analysis

“Gabe has done an excellent job of providing FEA analysis for several new products we are developing. He has been very resourceful in researching material properties and has provided extremely useful data enabling Semicoa to make critical decisions on new packages. His responses have always been very timely and he has been accommodating to the schedules we have set. His reports have been of a very high quality, so much that we have included them in a published paper and in press releases for new products. I highly recommend FEA SERVICES and Gabe and will continue to utilize his services in the future.”

Thomas Noll – SEMICOA – Costa Mesa, CA


Non-Linear FEA and Damage Tolerance

“Mr. Dambaugh supported the Damage Tolerance Team work efforts for NASA’s Constellation Program Upper Stage design and development efforts. He provided leadership in developing and executing assessment plans for various design issues. His development plans were thorough yet concise, without requiring an excessive set of analytic evaluations. His ability to formulate these plans quickly while coordinating customer needs was exemplary.”

Wayne Gregg – NASA/MSFC – Huntsville, AL


Joint Integrity

“The entire process from the initial model submission to the analysis of the results went very smoothly. Breaking the project down into two phases allowed us to understand the overall performance of our frames as well as focus on specific high-load areas in greater detail. The formatting of the results presentation saved me hours of prep time as I was able to use the actual file without editing for my discussions with upper management.”

Jaime Carrera, P.E. – VARIAN SEMICONDUCTOR – Austin, TX


Fatigue Durability and Forensics

“Mr. Dambaugh (of FEA SERVICES) was a pleasure to work with, and he got the job done within budget and ahead of time. He was diligent, insightful, professional, timely, polite, and a good teacher. Ours was an unintuitive, complex problem, but he handled it with ease. The revised component survived the abuse, and helped our engine become the first and only heavy fuel solution in its class ever to pass the US Army’s endurance qualification test for unmanned airplanes.”

Brian Callahan, Ph.D. – XRD, Inc. – Beaufort, SC


FEA System Development

“I was very impressed with the FE analysis methodology development FEA SERVICES provided our company. Technically they presented a unique proposal to a challenging problem. I found FEA SERVICES project management to be exceptional. Whereas I typically end up managing my outside FE analysis, FEA SERVICES provided a detailed time line and delivered all tasks on schedule at budget.”

Curt Lindstrom – ADAMS THERMAL SYSTEMS – Canton, SD


Process Simulation

“Gabe Dambaugh of FEA SERVICES was a pleasure to work with. He has an excellent grasp of engineering on a conceptual level that allowed a fast and effective approach to the problem. The time spent in developing models was directed by data created during the model process and Gabe was flexible and helpful in advising the best approaches to take. He even offered advice for experimental methods during the problem solving process. The end result was a model showing exactly what we experienced as failure location and mode. The model pointed us down a solution path not previously seen until the model and associated testing pointed in the right direction. We saved weeks of hypothetical-question based testing.”

Aaron Micetich – EGIDE USA – Cambridge, MD


FEA with Material Testing

“Your material analysis through FEA has proven very beneficial to a project of mine where we incorporated a common polymeric material into a new application using a non-standard forming process. The analysis results served well to reassure customers of the product robustness and safety. Sales of this product have contributed significantly to record company sales throughout last year. The investment in your services has paid for itself many times over.”

Wayne Bouldin – MEMBRANA – Charlotte, NC


Fatigue Durability

“The people at Callies Performance Products would like to thank all those at FEA SERVICES who were involved with the evaluation and development of our recently implemented crankshaft modifications. Your company’s support has greatly helped us in eliminating a long standing product weakness. Recommended changes in both material and design appear to have solved the problem. We appreciate the quick response and your attention to the details of our project.”

Best in class software


The SIMULIA Abaqus product suite consists of its three core products: Abaqus/Standard, Abaqus/Explicit and Abaqus/CAE (Complete Abaqus Environment). Also, with the new “Extended” products packaging, fatigue analysis with fe-safe and design optimization with Tosca are also provided at no extra up-charge.

Abaqus/Standard provides analysis technology to solve traditional implicit finite element analysis, including static, dynamic and thermal analyses, yet powered with the widest range of contact and other nonlinear options since the base code was originally written with nonlinear equations at the foundation.

Abaqus/Explicit provides Abaqus analysis technology focused on transient dynamics and quasi-static analysis using an explicit time integration, which is appropriate in many applications, such as drop tests, crushing, manufacturing processes or progressive failure simulation. Both Abaqus/Standard and Abaqus/Explicit can integrate with third party software or incorporate user subroutines for nearly limitless possibilities to simulate reality.

Abaqus/CAE provides a complete modeling and visualization environment for Abaqus analysis products. With access to CAD models, advanced meshing and visualization and the direct link Abaqus workflows, Abaqus/CAE provides an elegantly simple modeling environment for even complex simulations.


The fatigue analysis software, fe-safe, is the technical leader in fatigue analysis software used by leading companies in automotive, marine, defense, offshore, power generation, wind energy, medical, and many other industries. It is a powerful yet also easy to use with Finite Element models and provides reliable, accurate fatigue life predictions regardless of the complexity of the analysis.

Design optimization with Tosca, which can also support nonlinear features, is a flexible, modular software system for non-parametric structural optimization that provides topology, sizing, shape and bead optimization using industry standard finite element solvers.


Given the depth of its implicit and explicit solvers and its nonlinear foundations, most real world events can be simulated with Abaqus. The broad range of multiphysics capabilities includes fluid-structural interaction (FSI) solutions using XFLOW or other third party codes, such as StarCCM. Many other multiphysics simulations, such as with electromagnetics, is also fully supported. Of course, thermal-mechanical analysis has been a long time standard for Abaqus and in fact was the motivation for the initial program development.
