Abaqus/CAE Usage. Contact surface smoothing can be applied only to native geometry models in Abaqus/CAE . By default, Abaqus/CAE automatically detects all circumferential, spherical, and toroidal surfaces in the general contact domain that can be smoothed and applies the appropriate smoothing.
Contact is an integral aspect of the analysis and optimization techniques that is utilized to understand, model, predict, and optimize the behavior of physical structures and processes. In OptiStruct, a variety of Contact capabilities are available to help model different scenarios. The two main discretization options in OptiStruct that can be ...
ABAQUS/Standard automatically smoothes the surface normals of element-based master surfaces (see below) used in finite-sliding contact simulations, including those modeled with slide lines. You are expected to create smooth analytical rigid surfaces (see Defining analytical rigid surfaces, Section 2.3.4 ).
Contact smoothing is useful to increase accuracy of the contact solution. An enforced displacement to push two concentric rings toward each other to engage the contact is used. The usage of NLOUT entry allows you to study the progression of SPC force over successive increments. Figure 1. FE Model.
The effect of using several important contact settings such as contact stabilization, clearance, adjust and smoothing on both the results and the convergence behavior is considered. Figure 1. Illustration of the Model.
