Experimental study on the fracture behavior of AZ91D magnesium alloy under complex loading

Experimental study on the fracture behavior of AZ91D magnesium alloy under complex loading

In this study, quasi-static compression, tensile, shear, and combined compression-shear tests are conducted on cast AZ91D magnesium (Mg) alloy to study its fracture behavior. Shear-compression specimens are applied instead of complex loading device to obtained the fracture response of Mg alloy under...
