Abstract

During the assembly process of aluminum structures with welded joints, usually the life of the structure due to the unwanted stress of the welding process and possibly the presence of undesired defects due to the strength of the initial design of the reduced structure will cause cracking and eventually cause fracture near the support sections. ؛ In this paper, to prevent the propagation of microscopic cracks, first, based on field investigations, the exact location of crack damage in rigid floating structure with specific application is identified, and then numerical methods are used to investigate the behavior of model floating structure under cyclic or periodic impact loads. Due to the knocking of waves and firing c Has been discarded. In addition, by analyzing the data output, by changing the component parts of the rigid float superstructure, and by modifying the new positioning of the structural member locally, the optimal design has been achieved, and the new geometry design responds to the needs of the floating user and stops Growth is cracking.
