A cohesive network approach for modelling fibre and matrix damage in composite laminates
TL;DR: In this article, a high fidelity analysis approach is used to predict the failure process of notched composite structures by incorporating cohesive interface elements along potential failure paths, which form an interconnected network to account for the interaction between interlaminar and intralaminar failure modes.
Journal ArticleDOI
Modeling of nonlinear response in loading-unloading tests for fibrous composites under tension and compression
TL;DR: In this article, an approach is developed to predict the tension-compression asymmetry in plastic strain and anelastic strain, as well as the dependence of asymmetry on stress level and fiber orientation.
Journal ArticleDOI
Experimental investigation on different positional impact damages and shear-after-impact (SAI) behaviors of stiffened composite panels
TL;DR: In this article, the buckling and postbuckling performances of stiffened composite panels with different positional impact damage under in-plane shear load were investigated, and the most serious decline in buckling was caused by the combination of material properties degradation and debonding due to the impact damage.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.
