抄録

In order to evaluate damage state of randomly perforated sheets under biaxial deformation, a new method using the equivalent net stress derived from the damage tensor, which is obtained by the tessellation and stereological method, is proposed in this paper. Stress concentration around holes in a perforated sheet was calculated by the FE analysis and the comparison is made between the equivalent net stress and the results of the FE analysis. Equibiaxial tensile tests of perforated aluminum sheet were also carried out using the bulge testing equipment and the localized deformation between some holes in the sheet were observed. Both calculated and experimental results show that the proposed method can properly evaluate the damaged state of perforated sheet under biaxial loading.
