| Abstract: | ANSYS finite element analysis method was adopted to investigate the strength and stiffness of the edge cracked or centre cracked steel plates with a stop hole on the crack tip reinforced by bonded composite patches.Based on a relative stiffness concept,influence of the length of a crack on the stiffness of damaged plates was investigated.And the composite repairing effects for stiffness was studied.Introducing a concept of rising ratio of yielding load,a research of composite repairing effect for strength o... |
