Interactions of Multiple Cracks under Compression

MO Xiao-yi,XIE Min,TANG An-min,WANG Jing(Department of Engineering Mechanics,Xi'an University of Technology,Xi'an 710048,China)  
Combined the boundary conditions on the crack faces and the single value condition of displacement.The complex potentials solution of stress function for a crack with concentrated pseudo-forces on the crack faces was arrived.With the aid of "pseudo-force" method,the superposition technique and Chebyshev integral method,the "pseudo-force" was obtained,the multiple crack interaction was solved and the interaction effects were discussed.The interactions between two cracks or of many cracks on the same line were calculated,and the effect of the distance and the angle on the stress intensity factor was analyzed.
