THE STRESS INTENSITY FACTOR AND STRESS-CONCENTRATION FOR A FINITE PLATE WITH A SINGLE CRACK EMANATING FROM A HOLE

A full field solution for a finite plate containing a single hole-edge crack is developed by Muskhelishvili's complex variable method. In the derivation of the solution, the equations of equilibrium and compatibility, the traction free condition on crack surfaces, and the single value condition of displacement are satisfied. For a tension loaded rectangular plate with a central hole and a single edge crack, the stress intensity factor of the crack and the peak stress at the opposite hole edge are calculated through the treatment of boundary condition with the minimum potential energy principle. Calculations are made for several geometries and a number of crack lengths. © 1990.
