HAND SOLUTION OF ONE-DIMENSIONAL INELASTIC WAVE-PROPAGATION PROBLEMS.
Abstract
A method for obtaining a numerical solution to a wide variety of one-dimensional inelastic wave-propagation problems is discussed. The emphasis is on solutions to problems involving air-induced propagation in soil or rock resulting from a nuclear detonation under superseismic conditions. Emphasis is also placed on hand solutions obtained using a desk calculator and drafting instruments. The method is quite versatile in that it allows any pressure or kinematic condition at a boundary, any nonlinear and hysteretic material stress-strain curves, and any layering of different materials. The principal limitations of the method are that it does not treat viscoelastic material behavior, problems involving more than one-dimensional behavior, and problems in which strains and particle velocities are not relatively small. Two example problems are included: one shows the formation of a shock in a homogeneous medium, and the other shows wave propagation through a layered medium. (Author)
