Basics to implement user-defined materials (usrmat, umat) in LS-Dyna with Fortran

dolfinx_materials is a Python add-on package to the dolfinx interface to the FEniCSx project. It enables the user to define complex material constitutive behaviors which are not expressible using classical UFL operators.

A module containing elasto-plastic material models (Hill-Plasticity) with straightforward extension to various hardening laws.

Material model calibration and error estimation research code

User material for finite element programs implmentmenting 3D viscoelasticity of the standard linear solid type with parameters for temperature and radiation dose effects, with calibrations for vinyl nitrile foam.

Classical LAMinate theory for the lightweight design of structures and systems in PYthon

A collection of high-performance material constitutive models used in computational mechanics.
