# Path-dependent-Abaqus-model-for-the-analysis-of-composite-curing
This Project introduces a novel method for investigating cure-induced residual stresses in composite materials through a path-dependent model in Abaqus. The model is implemented within Abaqus CAE using various Fortran subroutines, including USDFLD, UMAT, HETVAL, UEXPAN, and DISP.
Since the Abaqus viscoelastic model is an advanced topic, some users may prefer simpler tools, one of the most well-known being the Abaqus path-dependent model. The Abaqus path-dependent curing model is simpler than the Abaqus viscoelastic curing model. In this project, we provided subroutine codes for the Abaqus path-dependent model for curing. We used the Abaqus path-dependent model to analyze residual stresses, strains, temperature, and the degree of cure in AS4/3501-6 prepreg. For verification, we compared the results with the reference solution. For example, as shown in the figure below, the stress during the curing process for AS4/3501-6 prepreg is well verified against the reference solution.
This repository contains the full .inp file along with some portions of the Fortran subroutines used in the Abaqus path-dependent curing model. The included subroutines are DISP, USDFLD, UMAT, HETVAL, and UEXPAN. For a more comprehensive understanding of these models, including theoretical insights and the complete Fortran codes for the Abaqus path-dependent curing model, refer to our full package. The access link is available in the "About" section on the right.
