Finite Element Analysis (FEA) and Computer Fluids Dynamics (CFD)
Our engineers are skilled in using Finite Element Analysis (FEA) and Computer Fluids Dynamics (CFD) to analyze the thermal-mechanical performance of different kind of systems.
Finite Element Analysis (FEA) based structural stress analysis is a valuable tool in the evaluation and optimization of product designs for systems including structural stress due to mechanical and thermal loading.
Since the majority of industrial components are made of metal, most FEA calculations involve metallic components. The analysis of metal components can be carried out by either linear or nonlinear stress analysis. Which analysis approach you use depends upon how far you want to push the design: If you want to ensure the geometry remains in the linear elastic range (that is, once the load is removed, the component returns to its original shape), then linear stress analysis may be applied, as long as the rotations and displacements are small relative to the geometry. For such an analysis, factor of safety (FoS) is a common design goal.
Evaluating the effects of post-yield load cycling on the geometry, a nonlinear stress analysis should be carried out. In this case, the impact of strain hardening on the residual stresses and permanent set (deformation) is of most interest.
The analysis of nonmetallic components (such as, plastic or rubber parts) should be carried out using nonlinear stress analysis methods, due to their complex load deformation relationship.
MACOGA uses FEA methods to calculate the displacements and stresses in our Expansion Joints due to operational loads such as:
