Using Viscoelastic and Path-Dependent Models for Analyzing the Curing Process in Fiber-Reinforced Composites With Abaqus subroutines

€ 290.0
Fiber-reinforced composites, widely used across various industries, consist of reinforcing fibers embedded in a matrix. During the curing process, this mixture transforms into a stable material. Curing is a critical step to ensure the durability and strength of the final product. In one of our intermediate packages, we used Abaqus to analyze the curing process in composites with linear elastic models. While these models are straightforward and user-friendly, their accuracy is limited because composites exhibit viscoelastic behavior during curing, rather than elastic behavior. To address this limitation, the current package introduces two more advanced and accurate models for analyzing residual stresses in composites: the viscoelastic model and the path-dependent model. These models offer significantly greater accuracy compared to linear elastic ones but involve added complexity. To simplify this complexity for users, the package begins with a comprehensive overview of the underlying theories and formulations for the viscoelastic and path-dependent models. It then provides detailed guidance on implementing these models using Abaqus subroutines. Finally, workshops are included to demonstrate how the viscoelastic model significantly improves the prediction of residual stresses in composites compared to the elastic models featured in our intermediate package.
