LS-Dyna Validated High Speed Tensile Rate Dependent Model

Test ID  
G-771V

    
Description  
Tensile experiments are carried out over a range of strain rates ranging into the high speed impact regime. Tests include 3 stress-strain measurements [M-204] in the .01-1 /s strain rate range and 2 high speed tensile stress-strain curves [M-232] in the 1-100 /s range covering a total strain rate range of 4 decades. Poisson's ratio is provided. The LS-DYNA material model file is created. Using this material model, the tensile test is simulated in LS-DYNA at various strain rates. The response is compared with the actual tensile tests that were performed.

    
Application  
Validated material models increase the confidence that the material behavior is being properly represented in the simulation. In conjunction with LS-DYNA, this data can be used to simulate the behavior of plastic components subjected to impact situations.
