Summary: A new constitutive model was developed in this study to predict the elastic behavior of plain weave textile composites using the finite element method. The model calculates the mechanical properties of the weave region and pure matrix region separately, and then imports them for FE analysis. The model was implemented as user-material subroutine code in ABAQUS FE software, showing capability in predicting effective elastic properties of plain weave fabric composites.

Summary: A new approach for predicting multiaxial fatigue based on a three-dimensional microplasticity-based constitutive theory has been proposed, which efficiently incorporates pre-full-yield microplastic deformations. By calibrating parameters using simple experiments, the developed theory and its finite element implementation demonstrate better predictive accuracy for fatigue life under proportional or non-proportional loading conditions.

Summary: A finite element model is developed to describe flow, stress, and crystallization in a filament stretching extensional rheometer (FiSER). The study shows that crystallization affects rheological behavior and the onset of crystallization during filament stretching is influenced by temperature, strain rate, and sample aspect ratio. Nucleation and structure formation are strongly dependent on these factors.
