Hyperelastic materials in ABAQUS

Hyperelastic materials are materials that can undergo large deformations without permanent damage. They are often used to model rubber-like materials, biological tissues, soft robots, and other applications that involve large strains. Hyperelastic materials can be characterized by a strain energy function, which relates the strain to the stored energy in the material. ABAQUS is a […]

UMAT and VUMAT: Advantages & Limitations

Overview of UMAT and VUMAT Subroutines The UMAT (User Material) and VUMAT (Vectorized User Material) subroutines are widely used in ABAQUS, a popular software suite for finite element analysis. These subroutines allow users to define custom material models and incorporate them into the simulation process. UMAT and VUMAT are user subroutines that allow users to […]

A Comparison of Different Solvers in ABAQUS

Abaqus is a popular finite element analysis (FEA) software used by engineers and researchers to simulate various physical phenomena. It offers a wide range of solvers to handle different types of problems, including linear and nonlinear statics, dynamics, fluids, electromagnetics, acoustics, and thermal analyses.
