Crack at a Hole in a Plate Subjected to Uniaxial Tension

Test Description

A plate with a crack at the hole of radius R is subjected to uniform tensile stress of 100MPa. Plane stress elements are used. Symmetry has been taken into account and only one quarter of the plate is modeled. U_Y=0 along un-cracked portion, U_X=0 along symmetry.
