Given the typically complex load deformation relationship of plastic and rubber components (the basic relationship assumption of Hooke’s Law is violated) nonlinear stress analysis is necessary when running stress analysis of plastic and rubber parts.
The plastic stress strain curve is required within the SOLIDWORKS material database in order to run plastic component stress analysis and gain the best results, the SOLIDWORKS material database comes prepopulated with said information and can also be customised to suit specific requirements.
You can choose from:
- Nonlinear elastic or hyper elastic Mooney-Rivlin or Ogden formulations (for rubber components)
- Hyper elastic Blatz-K formulations (for compressible polyurethane foam type rubbers)
SOLIDWORKS Simulation utilises FEA methods to determine the displacements and stresses in your products caused by operational loads such as:
- Contact between components
