Progressive failure analysis of 2×2 braided composites exhibiting multiscale heterogeneity

Progressive damage simulation of triaxially braided composite using a 3D meso-scale finite element model

“…In the past decade, finite element (FE) modeling of damage and failure has been gaining popularity. The progressive damage simulations of textile composites have been studied by several scholars [6][7][8][9][10][11]. Zako et al [12] gave a brief review of the damage analysis of woven composite materials, and proposed an anisotropic damage constitutive equation using the Murakami damage tensor.…”

Multi scale analysis by acoustic emission of damage mechanisms in natural fibre woven fabrics/epoxy composites.

“…Subsequently, the dominant mode of damage developed in each orientation has been associated to the corresponding a e-mail : claire.bonnafous@lmpm.ensma.fr 14th International Conference on Experimental Mechanics AE event amplitude. Damage mechanisms in woven fabric composites are much more complicated than in UD laminates because of the complex meso-structure of woven fabric composites [15][16]. Therefore, many authors have developed additional tests or additional experimental methods to study these composites [6,7,17].…”

Predicting the non-linear mechanical response of triaxial braided composites

“…The non-linear mechanical response of textile composites was investigated by several researchers based on idealised geometrical models. By exploiting symmetries and periodicity in the material microstructure, Tang and Whitcomb [5,6] derived a reduced unit cell (rUC) for biaxial braided composites. Owing to the model's computational efficiency, a sensitivity study of the progressive failure behaviour to the internal geometry was performed.…”
