Multi-scale failure analysis of plain-woven composites

Abstract

A numerical model capable of dealing with progressive degradation of plain woven composites in a computationally efficient manner is presented in this article. A semi-analytical homogenization method is used to derive effective properties of the composite from the material properties of the constituents. The progressive failure is described using nonlocal continuum damage mechanics where the driving internal variable for the damage is the nonlocal strain. The model was implemented into Abaqus/Explicit, where the failure of a longitudinal tension and an open hole tension specimens were simulated in a multi-scale manner and verified experimentally.

Micromechanical Modelling of Textile Composites

“…In this section, progressive failure analysis reported by Bacarreza et al in [102] progressive degradation of plain woven composite structures in a computationally efficient manner. It uses the semi-analytical homogenisation method presented in Section 1.2.1 to derive effective properties of plain woven composites from the material properties of its constituents.…”

“…The failure criteria used in [102] for predicting yarn bundle failure differentiates between the type and direction of the load, i.e., it is different for tension, compression and shear, and it is also different for different directions of the load whether it is aligned to the fibres or not.…”

“…The compressive strengths of polymer resins are always higher than the tensile strengths. In order to take that into account Bacarreza et al [102] adopted the isotropic damage model proposed by Mazars [108].…”

Numerical Analysis of Macro-Scale Mechanical Behaviors of 3D Orthogonal Woven Composites using a Voxel-Based Finite Element Model

“…For instance, Kwon YW et al [7] discussed the thermomechanical analysis of refractory woven fabric composites using a multi-scale analysis technique. Bacarreza et al [8] developed a semi-analytical homogenization method to predict the progressive degradation of plain woven composites. Also, the failure of the open hole tension specimens was simulated.…”

Mesh-objective two-scale finite element analysis of damage and failure in ceramic matrix composites

“…This method is numerically fast with the cost of inaccuracy particularly for components that experience high shear. Bacarreza et al [6] developed a semi-analytical homogenization method to model damage in woven composite materials. Effective material properties are derived and used in a progressive damage analysis.…”
