This paper deals with modeling of monotonic tensile test of Cu-ETP copper in numerical environment using finite element method. The research aims to verify the capabilities of LS-Dyna software in terms of modeling the strain hardening and damage of the material. The numerical analyses were proceeded by experimental tests to determine the materials constants of isotropic hardening model and constant required for modeling of material’s damage. Determined material constants were implemented into LS-Dyna environment using MAT_Damage_3 material model. The specimen model was built using eight-node hexahedrons. Both in case of experimental and numerical tests, the controlled parameter was displacement of the specimen. Obtained strain-stress curves were analyzed and conclusions were drawn.
