| For our long-term goal of understanding how metal connectors used for housing respond to hurricanes' wind load, we have conducted Finite Element Analysis (FEA) to compute the stress and strain distributions in tensile-loaded, aluminum and tin plates with holes.;The specimen is 20 - 25 mm wide, 0.1 - 10 mm thick, and 100 mm long in the direction of the tensile axis along which two holes are drilled. In addition, we have conducted tensile experiment using an optical interferometer and analyzed the in-plane strain field.;Comparison of the FEA and experiments indicate that band-like interferometric fringe patterns representing strain concentration coincide with the region where the von-Mises yield criterion is satisfied and experimental results are in good agreement with the corresponding FE simulation solutions. The optimal design of metal plate under given conditions is found.;Key words: Finite Element Method, White Band, Plasticity... |
