Creating zero-thickness cohesive elements is significantly simplified in the latest 2016 version of Abaqus. Viscous regularization can be directly added to cohesive formulation in order to improve convergence. 4.ĬZM is available in the form of cohesive surfaces or elements in two- and three-dimensional applications. Material degradation due to damage is governed by linear or exponential softening as illustrated in Fig. As one of the major commercial FE software programs, Abaqus is compatible with a lot of other in-house or commercially available FE codes.ĭamage initiation can be controlled by maximum stress/strain criterion or two-dimensional Hashin’s criteria. Abaqus Standard is used for problems solved by implicit schemes and Abaqus Explicit for high speed dynamic problems. Other subprograms for instance are Isight and Tosca for optimization or fe-safe for advanced fatigue analysis. Johannes Reiner, Reza Vaziri, in Comprehensive Composite Materials II, 2018 8.4.4.1 SIMULIA AbaqusĪbaqus is part of SIMULIA family of codes which is a multiphysics modeling and simulation software.
