Static Rigid-Plastic Analysis of Unstiffened Cylindrical Shells. Part 3. Shear Correction to Model Number III.
Abstract
The purpose of this report is to study the effect of shear on the damage experienced by an unstiffened circular cylindrical shell subjected to a static knife loading at the middle of its length. The ends of the cylinder are assumed fully fixed. The material constitutive model is rigid-plastic. The methodology can be applied to earlier models as proposed by Wierzbicki and Suh and by Moussouros. Like the earlier two rigid-plastic models this analysis only obtains global quantities and can result in large nondimensional dent values prior to reaching its limits of applicability. However, it is shown that the nondimensional load increases with the geometrical characteristic ratio of radius to thickness (a/h). This functional form was obtained here for the first time and represents a novel result. The report also shows that the present model compared well with experimental results....
