In many cases, the simulation focuses on a static load case. Static in this context refers to low deformation speeds of the part and thus low strain rates in the material. Our elasto-plastic material files describe the elasticity and plasticity behavior of the compound under these conditions.
They all include the first pseudo grain local failure (FPGF) mechanism to predict part failure and location. Customers will find files for every temperature and humidity rate required for their applications, together with files defined to take into account (saturated) material plasticization and aging in coolants.
Local stresses and strains vary within the part. Our elasto-plastic material laws including failure (abbreviated to EP_FPGF) are designed to describe realistically the behavior of TECHNYL® polyamides in general static load cases. For long-term loads or cyclic loads, creep and fatigue material models are recommended.
Typical fields of application include:
- Covers with gasket loads
- Mounting systems and fixations, e.g., for engines
- Automotive pedal systems like accelerator, clutch or brake pedals and their support
- Pump housings with inner pressure
- Oil filter modules and thermostat housings
- Snap fit assembly
Parts in contact with coolants and fluids are also considered taking into account aging phenomena like:
- Cool and pipes or pump housings with inner pressure
- Oil filter modules
- Thermostat housings
