Many mechanical stress simulations are possible with modern FEM (Finite Element Method) software. Physixfactor has conducted mechanical simulations for the industry ranging from linear mechanical stress analysis, modal analysis to non-linear analysis of hyperelastic materials. Complex geometries can be programmed easily in CAD (computer-aided design) software, and in this way Physixfactor is well equipped to tackle many virtual tests in order to reveal peak stress and propose improved designs. Static, dynamic and non-linear analyses are all feasible, depending on your needs.
Overview of some virtual test procedures:
- mechanical stress or strength calculations
- thermal expansion of materials, heat-analysis
- non linear materials. Plastic deformation, Mooney-Rivlin models etc.
- hyperelastic materials, such as rubber and thermal foils.
- contact analysis.
- modal analysis
- vibration analysis
Finite Element Analysis (FEA) can be applied in an early stage of the design process. If the right physics and interactions are applied to your model, the physical behavior can be tested. Stress concentrations, fatigue or other fields of interest can be studied. An important part within the FEM analyses is to take time to apply the right boundary conditions to your test model. In practice this can sometimes be cumbersome, and Physixfactor has build a data base of special boundary conditions which might be used on your models since 2005. The boundary conditions should reflect the real behavior in practice, and ideal boundaries might overdetermine some stresses or deflections in the system. Right from the beginning Physixfactor will discuss and analyse the situation and circumstances of your product.
There are many test characteristics possible, and if your specific tests are not mentioned on this website, please do not hesitate to contact Physixfactor.
