Abstract

Abstract

The relation between J-integral near model I crack tip in the orthotropic plate and displacement derivative is derived in this paper. Meanwhile,the relation between stress intensity factor K₁ and displacement is also given in this paper.With sticking film moire interferometry method,the three-point bending beam is tested,thus the values of J-integral and K₁ can be obtained.from the displacement field,and then the truth of relation formula between J-integral and K₁ in the orthotrtopic composite materials is experimentally verified.
- orthotropic composite material,
