LS-DYNA High Speed Foam Model (MAT_083 or MAT_163)

Test ID



Compressive experiments are carried out over a range of strain rates ranging from quasi-static to the high speed impact regime. Three low speed compressive tests are performed along with two high speed experiment covering a strain rate range of five decades. A tensile test is also performed to provide stability to the model and provide the tensile cutoff value. Data are analyzed for use in the LS-DYNA MAT_083 (Fu Chang) or MAT_163 model.

In conjunction with LS-DYNA, this data can be used to simulate the behavior of crushable or elastic foam components subjected to impact situations.
