Effect of shear on plastic denting of cylinders (Q1892291)

The purpose is to study the effect of ``inplane shear'' on the damage experienced by an unstiffened circular cylindrical shell subjected to static knife loading at the middle of its length. The ends of the cylinder are assumed to be fully fixed. The material constitutive model is rigid-plastic. Only ``local'' behavior is analyzed and global effects are neglected. It is shown that the nondimensional load increases with the geometrical characteristic ratio of radius to thickness.
