Description:     Dynamic punch test Aluminium 2024, MAT_224 
                 (*MAT_TABULATED_JOHNSON_COOK). Controlled dynamic testing is 
                 performed on a Split Hopkinson Bar (SHB) to examine failure
                 of Aluminium 2024. Dynamic punch testing at 20 m/s using two 
                 different punch shapes and a circular sample with D=14.56 mm 
                 and t=1.456 mm (10%)
