Abstract

In this paper, the three-dimensional finite element model of single and double micropores with complex shape of cast aluminum alloy was established based on ABAQUS. The three - dimensional finite element model of single and double micropores was established by using Johnson-Cook constitutive model. The finite element simulation of the penetration behavior of micro - holes with single complex shape micropores is carried out. The simulation results show that the maximum stress appears at the tip of the micropores under the external load, and the micro-cracks are induced at the tip of the micro-pits with the nucleation and growth of the micropores.The maximum stress appears in the radial maximum size of the cavity wall and the dimple tip of the micropores. Under the action of the external load, the deformation of the double-hole micropores increases with the symmetry of the double- Center formed through
