PERFORMANCE OF OPTIMIZED LARGE DEFORMABLE ELASTIC PLATES UNDER TENSILE LOAD

Abstract

This study investigates Large Deformable Elastic Plates (LDEPs), which exhibit significant elasticity and can return to their original shape even after large deformations. The concept of Large Deformable Elastic Braces (LDEBs) is applicable and explores the elastic properties of LDEPs, which minimize residual deformation of the model. This study conducts both experimental tests and finite element method (FEM) analyses to find the performance of LDEPs under tensile loads for conditions of material and geometric non-linearity. However, topology optimization of four-column formulation methods has been established, and the findings demonstrate the significant potential of LDEPs in improving earthquake resistance. This study also focused on the considerable effect of residual stress and material hardening due to laser cutting. The final key conclusion is to develop an equation for yielding deformation and yielding force of LDEPs, verified by numerical analysis and experimental test results. The practical application of these components underscores their suitability in earthquake-prone regions.
