Using the plasticity connector factor (i.e., defining an effective crack length) account for crack tip plasticity effects for the following problem and calculate the critical load Pc at fracture. The elastic solution is σy(x,0)=πPl2x21x<l.  The fracture toughness and yield strength of the material are, respectively, Kc and σys​. Compare your solution with the elastic one and comment on the differences.
