Tensile and Compressive Properties for Crashworthiness Assessment of a Large AZ31 Extrusion
Tensile and compressive tests of a large AZ31 extrusion were performed along extrusion and long transverse directions over a range of strain rate (0.00075 s-1 to 9 s-1) and temperature (100°C to -143°C). The effects of strain rate, temperature, sample orientation and load direction (tension or compression) on mechanical properties are reported and discussed. The yield strength of tensile samples along the extrusion direction can be described by a constitutive equation using the conventional rate parameter for thermally activated deformation.
