Abstract

Many engineering problems involve contact between two or more components, in these problems, when two objects come into contact with each other, on the surface of the perpendicular to the contact force between two objects. If there is friction between contact surface, shear may be produced to prevent the tangential motion of the object. This article mainly using ABAQUS software to ellipsoid and rigid semi-infinite discusses the general contact problem, because the ellipsoid is before and after the left and right sides is symmetrical three-dimensional entity, so take a quarter analysis to it, that not only the calculation results of convenient and intuitive. Before the adoption of the first material is defined as elastic material modeling, calculation, after processing to analyze between ellipsoid and general contact, using a variety of methods to discuss contact problem. Than elastic yield limit, the resulting data will reopen assignment for elastic-plastic materials, imitates the elastic analysis method of elastic-plastic analysis, get the right result.

Key words: Contact; ABAQUS; Elastic-plastic; Yield limit
