The effect of porosity and pore shape on the mechanical properties Of Nanoporous Aluminium Single Crystal, Using molecular dynamics simulations

In this research, the effect of porosity and pore shape on mechanical behaviour Of nanoporous aluminium single crystal ( open and close cell) were studied. In fact, by combining molecular dynamics simulations with house codes, the mechanical behaviour of the foams were measured. The results showed that by increasing the porosity, the Young’s modulus, yield strength and ultimate tensile strength were decreased. Also by changing the pore shape from spherical to cylindrical Young’s modulus, yield strength and ultimate tensile strength were decreased with fixed relative mass density. Also, the results indicated that the nanoporous deformation was accompanied by nucleation and growth of cracks near the void surface along the loading.
