Plane Nonstationary Problem of Motion of the Surface Load Over an Elastic Half Space

We study the response of an elastic half space to the action of a normal concentrated load moving along its boundary. In the general case, the law of motion of the load is arbitrary. The solution of the problem is based on the principle of superposition. We construct a one-dimensional integral representation of the solution. The results are obtained for the case of uniform motion of the load. We show the dependence of the solution on the velocity of motion of the load, reveal singularities of the solution, and present graphic results.
