Damage analysis and mechanical response of as-received and heat-treated Nicalon/CAS-II glass-ceramic matrix composites
… in air for 100 hours. Changes at the fiber/matrix interface/interphase due to post-processing heat treatments were also characterized. The combined effect of fiber debonding and transverse matrix cracking in both 90° and 0° plies plays an important role in damage development in [0/90]₄₅ …

Interfacial Mechanics in Fiber-Reinforced Composites: Mechanics of Single and Multiple Cracks in CMCs
… of the interface between the fibers and matrix in ceramic matrix composites (CMCs) are studied. The first issue is the competition between crack deflection and penetration at the fiber/matrix interface. When a matrix crack, the first fracture mode in a CMC, reaches the interface, two …

Multi-Class 3D Segmentation of Progressive Damage in Advanced Composites using Deep Learning
… three categories, each of them manifesting as a crack of some sort: (i) delamination (interlaminar cracking), (ii) matrix cracking, and (iii) fiber breakage (crack through fiber). At present, X-ray computed tomography (CT) performed to observe these complex damage mechanisms in 3D and 4D (3D …

A generalized finite element method for three-dimensional fractures in fiber-reinforced composites
… for three-dimensional modeling and simulation of crack propagation in fiber-reinforced composites. Fibers are discretely modeled using a modified formulation of the Embedded Reinforcement with bond Slip (mERS) that allows its combination with the GFEM where fractures are represented using …

Analysis of matrix damage in single fiber composites
… equal axial strains in the fiber and the matrix, if there are no initial cracks and the fiber/matrix interface is perfectly bonded. With further increase in the load, the fiber or the matrix will crack depending on the failure strains or the fiber/matrix interface w ill debond depending on …

Durability of Ceramic Matrix Composites at Elevated Temperatures: Experimental Studies and Predictive Modeling
… and strength of an oxide/oxide ceramic matrix composite system under stress-rupture conditions were studied both experimentally and analytically. A rupture model for unidirectional composites which incorporates fiber strength statistics, fiber degradation, and matrix damage was derived. …

Micromechanics of ultra-high molecular weight polyethylene fibre composites
… of strong UHMWPE fibres with a soft compliant matrix. The extreme anisotropy caused by the mismatch between the stiffness and strength of the fibres and the matrix resulted in unique deformation and failure mechanisms which cannot be found in conventional engineering materials. Therefore, the …

Resistance of Carbon Fibre Reinforced Composites to Quasi-static and Ballistic Perforation
… mechanism, CFRP cross-ply coupons with various matrix shear strengths were subjected to uniaxial out-of-plane compression between lubricated platens, while CFRP cross-ply beams were subjected to quasi-static indentation between a flat bottom indentor and a lubricated back support. The …
