<正>Creep of squeeze-cast Mg-3Y-2Nd-1Zn-1Mn alloy was investigated at the constant load in the stress range of 30-80 MPa. Tensile creep tests were performed at
<正>The microstructures and mechanical properties of a new Mg-6%Zn-1%Mn(mass fraction) wrought magnesium alloy were studied,which could be extruded smoothly at
In view of the non-local phenomena appearing in the rock and concrete-like materials, the non-local damage and fracture model of rock and concrete-like material
