- Abstract
Static three-point bending test of Web-core steel sandwich panel was performed. The deformation and failure of the sandwich structure were investigated,together with the finite element simulations, which considered the weld width of the laser-welded T-joint. The results indicate that the initial yield load is 25 kN, and the maximum bending load is 54 kN. The deformation could be divided into three stages. The first stage is the elastic deformation when the load less than the yield load. The second stage is the plasticity deformation when the load is larger than the yield load but less than the maximum load. It is suggested that the higher stability and load-carrying capacity of the sandwich panel. The third stage is the failure process. The failure of the sandwich panel can be ascribed preliminarily to the local bucking on the face plate under a large bending load. However, the FEM result suggested the failure mode is the T-joint failure, because the plasticity rings were formed before the bucking of the face plate. The laser welded T-joint is so important that the structural design shouldn't unnoticed the weld geometrical features.
