Finite element analysis of Al-Mg alloy elasto-plastic behavior and fracture during dynamic perforation

A mechanical behavior of Al-Mg alloy subjected to the dynamic perforation test at different strain rates was described by numerical modelling. Deformation - fracture process was investigated. Dynamic penetration tests were carried out; stress-strain curves were obtained at different rates. Johnson-C...

Description
Summary:A mechanical behavior of Al-Mg alloy subjected to the dynamic perforation test at different strain rates was described by numerical modelling. Deformation - fracture process was investigated. Dynamic penetration tests were carried out; stress-strain curves were obtained at different rates. Johnson-Cook material and failure models were used. Model parameters have been determined experimentally. Numerical data were compared with experimental data, obtained by penetration tests with different strain rates. Finite element results are in good agreement with the experimentally obtained results under the domain of the strain rates considered in the present study.
