The Effect of the Area Ratio and the Distance Ratio on Bending Stiffness of Two Rectangular Plates Spot-Welded

면적비와 거리비가 점용접된 두 사각평판의 굽힘강성에 미치는 영향

The mechanical behavior of two rectangular plates spot-welded under bending is investigated in detail. The focus of the analysis is to evaluate the effect of thickness of reinforced plates with equivalent thickness. The results of this investigation are compared from detailed finite element analysis and experiments of the plates spot-welded for various parameters, such as aspect ratio, area ratio, and distance ratio of spot-welding points. The study is carried out using the equivalent thickness of the reinforced plates spot-welded.
