Abaqus implementation (through UEL subroutine) of the incremental energy/dissipation based arc-length method. Suitable for physically non-linear, geometrically linear solid mechanics problems solved through an implicit solution algorithm. The zip file includes a read-me pdf giving information about how to use the files. The details are presented in the following paper : Author : İ.

This library contains several of user material subroutines for implicit quasi-static (UMAT) and explicit dynamic (VUMAT) versions of the Abaqus solver. The project web site: http://abumpack.sf.net. The Abaqus is a proprietary finite element (FE) code ( http://www.3ds.com/products-services/simulia/products/abaqus/). Users can write subroutines for use with the Abaqus. Linear elastic, isotropic hardening plasticity, Gurson-Tvergaard-Needleman (GTN), Rousselier constitutive models are provided. ...

A phase-field model for brittle fracture is implemented in the commercial finite element software Abaqus by means of UEL subroutine. The phase-field method considerably reduces the implementation complexity for fracture problems as it removes the need for numerical tracking of discontinuities in the displacement field that are characteristic of discrete crack methods. This is accomplished by replacing the sharp discontinuities with a scalar damage phase-field representing the diffuse crack topology wherein the amount of diffusion is controlled by a regularization parameter. ...
