Abstract

The purpose of this study is to propose a new numerical modeling of single-lap joints of CFRP laminated composites. The eigenvibration mode is always three-dimensional behavior deformation which includes in-plane and out-plane deformations. This indicates that the finite element analysis requires three- dimensional solid element. In case that the adherend plane structure is modeled by the conventional solid element, the huge elements and huge solution time are unavoidable. Therefore, we proposed the new numerical model in this study. This model is construction of orthtropic-shell element and beam element, which represent adherend and adhesive, respectively. Shell elements ar
