This paper discusses the characterization of temperature-dependent tensile and flexural rigidities for Dyneema® HB80, a cross-ply thermoplastic lamina. The low coefficient of friction of this material posed a challenge to securing specimens during t

Two models for completing structural analyses of cured fabric-reinforced composites that link back to a forming simulation are investigated. The objective of each model is to seamlessly use the predicted geometries of the textile plies to generate a

A study to investigate the factors that contribute to the variation among the stiffnesses of consolidated composite plates reinforced by plain-weave fabrics with various degrees of in-plane shear is presented. The first part of the two-part study foc

Numerical investigations were pursued in an effort to understand the relationship between changes in the stiffness of plain-weave fabric-reinforced plates and the degree of in-plane shear within the fabric reinforcement. These numerical studies were

A hybrid finite element model using a discrete mesoscopic approach was previously developed and has since demonstrated its ability to capture the tensile and shear behaviors of textile reinforcements for composites. The aim of the present research is

This paper presents a methodology for extending the use of the beam-shell forming model to predict the structural properties of the composite part. After the forming simulation has been performed, the material definition will be changed such that the
