Anchoring Effect of Oblique Crack under Axial Tension Load

The total improved potential energy of the system with anchor was modified by meshless method. The discrete equations of the system were derived. According to the variation principle, the anchorage problem of plate with oblique crack was studied by numerical under axial tension. Based on different elastic modulus of the anchor and various anchoring schemes, the equivalent elastic modulus of the system with anchor, the maximum stress at crack tip, and the rupture loads were researched. The best solutions were provided for improving equivalent elastic modulus and rupture load of structure. The results showed that elastic modulus of anchoring material has essential effect on inhibiting crack propagation and improving mechanical properties of jointed crack mass. The elastic modulus of anchoring material was 1-30 times as elastic modulus of the base material, which can achieve better anchoring effect.
