| Abstract: | The fiber reinforced resin matrix composites are a kind of structural material with high specific strength and high specific rigidity.It is very important for engineering application and material design to investigate the relationship between the crack and strength of composites.Based on a mesoscopic-mechanical model,the influences of the length and crack tip position of mode I crack on the stress distribution and stress intensity factor are analyzed by means of the finite element method,and then the relationship among the crack initiation load,crack length and crack tip position is obtained. |
| Keywords: | composites crack strength mesoscopic-mechanical model numerical simulation |
