ELASTIC-PLASTIC ANALYTICAL SOLUTION FOR AN ECCENTRIC CRACK LOADED BY A PAIR OF TENSILE POINT FORCES
The near crack line analysis method is used to investigate an eccentric crack loaded by a pair of tensile point forces in a finite plate in an elastic-perfectly plastic materials, and the analytical solution are obtained under plane stress condition in this paper. The solutions include: the elastic-plastic stress fields near crack line, law that the length of the plastic zone along the crack line is varied with an external loads, the maximum lengths of the plastic zone, the bearing capacity of a finite plate with an eccentric crack loaded by a pair of tensile point forces, and the unit normal vector of the elastic-plastic boundary near the crack line. The results of this paper are sufficiently precise near the crack line because the assumptions of the small scale yielding theory have not been made and no other assumption has been taken.
