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.
This project presents an innovative approach for examining residual stresses in composites: The Abaqus viscoelastic model for curing. The implementation of the model is carried out in Abaqus CAE, utilizing Fortran subroutines such as USDFLD, UMAT, HETVAL, UEXPAN, and DISP.
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.
