Modeling contact interference fits in Abaqus/Standard

Interference fits in Abaqus/Standard:

  • occur by default when the contact formulation computes overclosures between surfaces in the initial configuration of a model;

  • are resolved in the first increment of a step by default;

  • can be gradually resolved over multiple increments;

  • result in stresses and strains in a model as overclosures are resolved;

  • can be specified for both surface-based contact pairs and contact elements; and

  • cannot be specified for self-contact.

Abaqus/Standard offers alternative methods to resolve initial overclosures with strain-free adjustments and to model specific overclosures or clearances different from those calculated from the initial configuration. These methods are discussed in Adjusting initial surface positions and specifying initial clearances in Abaqus/Standard contact pairs.
