What Is Abaqus?

Abaqus is a leading FEA software developed by Dassault Systèmes under the SIMULIA brand. It provides advanced tools for modeling, analyzing, and visualizing physical behaviors of products and structures in virtual environments.

Originally introduced in the late 1970s, Abaqus has grown into a robust suite of applications that support:

• Linear and nonlinear structural analysis
• Heat transfer and thermal simulations
• Dynamic and static simulations
• Coupled multiphysics problems

Whether you’re working with metal fatigue, crash tests, or composite materials, Abaqus delivers a powerful simulation environment that supports the entire product lifecycle.

Key Features of Abaqus

1. Advanced Nonlinear Capabilities

Abaqus stands out for its nonlinear analysis engine, allowing engineers to simulate material plasticity, large deformations, and contact problems with high fidelity.

• Handles large-strain behaviors
• Supports complex contact interactions
• Accurately predicts real-world material performance

2. Multiphysics Simulation

Need to combine thermal, structural, and electrical phenomena in one simulation? Abaqus enables multiphysics analysis through native capabilities and integration with other software tools.

Examples include:

• Thermal-mechanical coupling
• Piezoelectric effects
• Fluid-structure interactions (FSI) via co-simulation

3. Robust Material Modeling

With an extensive library of predefined material models and support for user-defined materials (via UMAT/VUMAT), Abaqus gives you unmatched control over how your materials behave under different conditions.

Supports:

• Metals, polymers, composites, foams
• Viscoelastic and hyperelastic models
• Damage initiation and evolution

4. High-Performance Computing (HPC)

For large-scale simulations, Abaqus supports parallel computing and distributed processing, significantly reducing simulation time. This is crucial when working with high-resolution meshes or running batch simulations.
