Analysis high strain rate fracture of polyamide6 (Nylon6) in a finite element software?

15 January 2019 1 667 Report

Does every body know high strain rate fracture model for polyamide6 (Nylon6) reinforced by 10% glass fiber to use in a finite element software? Does every body know Johnson-Cook constants for this problem?

Rolf-Hugo Kirkvik

When we analyze and dissect failed unbonded flexible pipes and umbilicals from the offshore industry the bending strain at nominal dimensions for polyamide (PA) and polyethylene (PE) have normally exceeded around 7-10 %. Limits for static and dynamic applications are different, also for materials such as polyvinylidene fluoride (PVDF).
