1.1.12 Crushing of a pipe

Product: ABAQUS/Standard  

Extreme accident analysis of piping systems sometimes requires knowledge of the behavior of a pipe section as it is crushed. The simplest such investigation is discussed in this example: the crushing of a long, straight pipe between two flat, frictionless anvils. The objectives are to establish the load-deflection response of the pipe and to describe the overall deformation of the section, since this may greatly affect fluid flow through the pipe. The example also provides a simple demonstration of the capabilities of ABAQUS for modeling contact problems between deformable bodies and rigid, impenetrable surfaces.
