Comparison of Abaqus Library, UMAT, and Analytical Solution for Neo-Hookean Hyperelastic Material Under Large Deformations

The UMAT subroutine in Abaqus serves as a solution for modeling materials that cannot be accurately represented using the standard Abaqus material library. For this project, we utilized this subroutine to study a 3D isotropic isothermal beam. Additional projects in this field can also be accessed on the following link.

The VUMAT subroutine in Abaqus provides an effective approach for simulating materials that are not adequately captured by the standard Abaqus material library. In this study, we applied this subroutine to analyze a 3D isotropic isothermal beam. Further projects related to this domain can be explored at the link provided below.

The UMAT subroutine is a tool in Abaqus that can be used when a material cannot be adequately modeled using the Abaqus material library. In this project, we employed this subroutine to evaluate the Tsai-Hill failure criterion in composites. Additional projects in this field can also be accessed on the following link.

In this project, we modeled the fatigue behavior of a composite material in 3D space using the UMAT subroutine in Abaqus. The Abaqus .inp file and part of the UMAT subroutine are provided. To access the video tutorial and all the modeling files for this project, click the link below.

This study introduces a novel method for analyzing residual stresses in composite materials: the Abaqus path-dependent curing model. The model is implemented within Abaqus CAE using Fortran subroutines like USDFLD, UMAT, HETVAL, UEXPAN, and DISP.
