Abstract
Nowadays, damage models are widely used in order to simulate and predict the failure points of parts in production processes, as well as to examine the damage caused to complex parts during collision. The purpose of this research is to determine the constants of the material model and GISSMO damage model for aluminum 2024. For this purpose, the data of experimental tests conducted on six tested samples (standard tensile and uniaxial compression samples, notched samples and punch test) were used. Then, by estimating the value of the failure strain in each sample from the experimental data, the dependence of the failure plastic strain on the state of stress in the GISSMO damage model was determined. In the following, the proposed damage model was used to simulate the experimental tests performed in the LS-DYNA software. The accuracy of the obtained numerical results shows that the method presented in the present research can be used to express the fracture behavior of other metals in different stress states.
