| Abstract: | ANSYS finite element analysis method was adopted to study the fatigue life of steel plates with an edge crack or a centre crack including a preventing break hole on the end point of the crack or steel plate with a cut.Influence of the length of a crack on the fatigue life of damaged plates was investigated.A research of carbon fiber reinforced composite patch repair effect for fatigue life of 3 kinds of damaged steel plates was presented. |
