Effects of non-uniform strains on tensile fracture of fiber-reinforced ceramic–matrix composites have not been satisfactorily explained by existing mechanics-based models. In this paper, we use an exact model of fiber fragmentation under global load sharin ...
Nanofibers used in current ceramic matrix composites (CMCs) are usually wavy and of finite length. Here, a shear-lag model for predicting the tensile strength and work of fracture of a composite containing a "single matrix crack", as a function of all the ...
By combining focused ion beam milling methods with microtesting techniques and finite element simulation we probe the strength of microscopic alumina phases that can be used as reinforcements in the production of metal matrix composite materials. We presen ...
Constitutive models for fiber-reinforced ceramic-matrix composites (CMCs) are needed to enable implementation of these materials in future engineering systems. One such constitutive model, developed by Genin and Hutchinson [1], is based on a phenomenologic ...
Here we present a processing route to produce multi-structured ceramic foams based on the combination of particle-stabilized foams with polymeric sponges to produce positive and negative templating structures. Polyester sponges are infiltrated with freshly ...
In metal matrix composites, a metal is combined with another, often nonmetallic, phase to produce a novel material having attractive engineering attributes of its own. A subject of much research in the 1980s and 1990s, this class of materials has, in the p ...
A model for predicting composite material strength degradation under elevated and high temperatures is proposed. This model is based on the morphology of the mixture of materials in different states. The degradation of resin-dominated shear strength can be ...
The tensile strength and ductility of fiber-reinforced composites containing ductile metal fibers is studied using a multiscale approach and compared to the performance of an identical composite containing elastic fibers. A finite element model of stress r ...
This study contributes to our understanding of the damage evolution and fracture behaviour of two-phase materials that combine brittle particles with a ductile matrix. We focus on model composites roughly half-ceramic/half-metal that are produced in-house ...
A statistical model for fracture of aligned-whisker-reinforced metals was used to interpret tensile data of a TiB-reinforced titanium alloy. From this analysis, a TiB whisker strength of 8.0 GPa with a Weibull modulus of 2 was predicted. The analysis is co ...
