Plastic and Rubber Part Analysis
Tightly integrated with SolidWorks CAD, stress analysis of plastic and rubber parts using SolidWorks Simulation can be a regular part of your design process—reducing the need for costly prototypes, eliminating rework and delays, and saving time and development costs.
Plastic and Rubber Part Stress Analysis Overview
The stress analysis of plastic and rubber components, or assemblies containing plastic or rubber parts, requires the use of nonlinear stress analysis methods, since these types if parts generally have a complex load deformation relationship (that is, the basic relationship assumption of Hooke’s Law is violated).
To carry out plastic component stress analysis, the plastic stress-strain curve must be known and entered into the SolidWorks material database to achieve the best results. This database is easily customizable to include your particular material 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 uses finite element analysis (FEA) methods to discretize design components into solid, shell, or beam elements and applies nonlinear stress analysis to determine the response of parts and assemblies due to the effect of:
- Contact between components
Loads can be imported from thermal and Simulation studies to perform multiphysics analysis.
