ABAQUS is a suite of finite element analysis software for computational mechanics modelling and simulations. The main analysis modules are ABAQUS/Standard and ABAQUS/Explicit. ABAQUS/CAE is the integrated graphical interface to the software for pre- and post-processing of data. The analysis modules will also run well on multi-processor systems and supports parallel computations.

ABAQUS/Standard is a general-purpose, finite element program designed for advanced linear and nonlinear engineering analysis applications. The program features very general geometry modeling capabilities (two- and three-dimensional continua, beams, membranes, shells, trusses, cables, gaps, etc.), a large library of materials (isotropic and anisotropic elasticity, visco-elasticity, hyper-elasticity, hypo-elasticity, foam elasticity, plasticity, metal plasticity, visco-plasticity, soil plasticity, reinforced concrete with cracking and crushing, etc.), and a broad range of procedures (static and dynamic stress, transient and steady-state heat transfer, fully coupled temperature/stress, fully coupled pore fluid flow/stress, large eigenvalue problem solution, Riks method for unstable post-buckling response, impact solution, acoustics, super elements and substructuring, etc.)

All of the response-history procedures offer automatic time-stepping. The program is designed for ease of use on complex problems and has a simple input language with comprehensive data checking, as well as a wide range of pre- and post-processing interactive (output display) options.

ABAQUS/Explicit is a transient dynamics program designed specifically to serve advanced nonlinear structural analysis needs. ABAQUS/Explicit has the standard interface familiar to ABAQUS users and is highly optimised for computational performance.

ABAQUS/Explicit has well developed element and material libraries. Element formulations include beams, shells, and continuum elements allowing finite rotation and finite strain calculations. Material models include rubber elasticity and plasticity for metals, foam and soils, equations of state, and a user subroutine interface for user material definition. Adiabatic heat generation due to inelasticity and a ductile failure model are also available.

ABAQUS/Explicit automatically controls the step size to satisfy stability limit requirements. The program uses the standard ABAQUS program definition language. A complete set of plotting options, print controls, and versatile restart features are included, as well as extensive post-processing capabilities.

Typical ABAQUS/Explicit applications include vehicle crashworthiness studies, structural component evaluation, metal-forming processes, and high energy, detonation calculations.
