2.2.3 Infinite elements: circular load on half-space

Product: ABAQUS/Standard  

This example was suggested by Lynn and Hadid (1981) and concerns the problem of an elastic half-space subjected to a uniform pressure load. The purpose of the example is to compare the performance of different coupled finite/infinite element meshes with the analytical solution given by Timoshenko and Goodier (1970). For comparison purposes a mesh of finite elements only is also used.
