Theory of stress distribution caused by side wall impact on glass containers

Abstract

The stresses and strains in a cylinder subjected to point loads applied at each end of a diameter can be calculated from shell theory if the load distribution is represented by a double Fourier series. The analysis is applied to the calculation of stresses produced by impact on the side wall of a glass container. In doing so, it is assumed that the impact is a relatively slow event and that all the kinetic energy of impact is converted into strain energy in the container at the instant of maximum deformation. The experimental information available is not sufficiently detailed to make possible an exact comparison with the calculated stresses. Nevertheless the degree of agreement is good enough to suggest that the method which has been followed is satisfactory. The computer program which has been developed is a simple one and has small storage requirements.
