Abstract

In order to study the mechanical properties of aluminum alloy, this paper adopts the birth-death element method (BDEM) to numerically analyze the behavior of tensile cracking of aluminum alloy specimens. A finite element model was established using Abaqus, and the BDEM were set in the deformation region. The results show that the BDEM accurately simulates the cracking behavior of the aluminum alloy. The specimen began to fracture when the experimental time was 18 s. The maximum Mises stress during the whole tensile process is 445.3 MPa. Compared with the traditional mechanical experiments, this method can obtain the stress/strain data during the large-scale plastic deformation of the aluminum alloy before rupture, which provides data support for the design and optimization of aluminum alloy parts.
