Action of Nonaxisymmetric Dynamic Loads on a Circular Hole in the Infinite Elastic Plane

摘要

A modified finite-difference method with respect to time and the method of Fourier series with respect to the angular variable are used to solve a plane dynamic problem of the elasticity theory on the action of nonaxisymmetric loads on the boundary of a circular hole in the infinite plane. The distribution of stress is determined. The time dependence of the stress concentration on the boundary of a circular hole is numerically found for various Poisson's ratios and the load distributed according to a certain law.
