Abstract

Two different sizes of the perforations in a metal sheet were chosen resulting essentially in a structure that was held together by links of varying thickness. A perforated sheet of the chosen metal was held together by thin links, while another was held together by thick links. The two designs of the perforated metal sheet were made possible using ABAQUS [version 6.13.2]. The specific metal chosen for this study was two steels having varying degree of high strength, i.e., an alloy steel and a carbon steel. The method of finite elements in synergism with a numerical approach was used to analyze the mechanical response of the perforated metal sheets when subjected to the influence of an external mechanical stimulus, such as, load that is applied in tension. For five different levels of the applied load, as a function of yield load of the candidate steel, the stresses, strains and resultant displacements induced in both the links and at nodal points were systematically determined. With the aid of numerical analysis, the mechanical behavior of the chosen steel structure, which was held together by a network of links, was systematically studied under the influence of an external mechanical stimulus, i.e., applied load. For each situation, i.e., thin links and thick links, the response kinetics under the influence of an external load was determined for the case of both symmetric loading and asymmetric loading.
