Gabe Dambaugh of FEA Services is being introduced by Ken Wong of Design Engineering (DE247) during webcast to discuss trends in FEA technology and usage.

The demand on FEA models is constantly increasing which in turn increases the demand for running such simulations faster and faster.  Hardware advances always assist in this endeavor, yet the basics of systematic and intuitive engineering to setup FE models is still the key.

Incorporating Multiphysics in FEA models is becoming more of a “norm” as opposed to being considered “advanced”.  In short, more real-world realism is becoming the expectation for simulation engineers.

Often asked is “when should a company seek out-of-house” help (i.e., FEA consultants) to tackle important FEA tasks?”  Very often it comes down to simple economics.

Cloud computing.  It’s not for everyone.

WHITE PAPER – HIGH STRENGTH METAL FATIGUE

High strength steels and other high strength metals are inherently damage intolerant which renders them susceptible to a wide statistical range of apparent strength results, especially under fatigue conditions. The correlation to rolling bearing fatigue and methods is also presented.

WHITE PAPER – FATIGUE WITH FEA PRIMER

Evolving methods using modern CAE technologies such as FEA have been successfully employed by Engineers in most industries to reduce part level fatigue failures. Top level explanations of vital aspects of utilizing FEA to mitigate fatigue based failures are provided for Design Engineers and Managers as they ramp up on internal analysis capabilities.

WHITE PAPER – HEAT EXCHANGER (HX) STRESS ANALYSIS

Heat exchanger (HX) designs which incorporate cooling fins often have many fins to maximize the total surface area for the cooling effect exchanged to the fluid. It is exactly this rather large amount of surface area which makes the development of a 3D finite element model an imposing endeavor due to the extreme number of nodes/elements required if the entire HX assembly is to be analyzed. Robust methods are presented to not only capture the deformation of the assembly but to also provide good convergence on the critical stresses in the areas of interest.

WHITE PAPER – HX FATIGUE ANALYSIS INDUSTRY STUDY

Heat exchanger (HX) designs which incorporate cooling fins often have a many fins to maximize the total surface area for the cooling effect exchanged to the fluid. It is exactly this rather large amount of surface area which makes the development of a 3D finite element model an imposing endeavor due to the extreme number of nodes/elements required if the entire HX assembly is to be analyzed. We quickly review a robust method to not only capture the deformations and critical stresses of the application, but also carry the analysis forward to a fatigue assessment and its correlation to subsequent lab testing of the HX unit.
