Unlock the full power of finite strain simulations with our cutting-edge ABAQUS UMAT subroutine, designed for engineers, researchers, and innovators tackling large deformations in real-world scenarios.
Why This UMAT is a Must-Have for Nonlinear Pros:
- Finite Deformation Framework: Seamlessly integrates with ABAQUS’s NLGEOM=ON for large strain accuracy. Computes stress using the deformation gradient, velocity gradient, and Jaumann rate of Cauchy stress, ensuring objectivity under massive rotations and stretches.
- Customizable for Your Needs: Pre-built for 3D problems, but easily adaptable to your custom constitutive laws.
- Proven in Action: Handles geometric non-linearities and validated against ABAQUS solver.
- User-Friendly Package: Includes Fortran source code, sample INP files, step-by-step integration guide, and test models.
- Complete documentation: Includes theory, implementation, and coding procedure.
