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 ...
Nowadays, composite materials are increasingly used in high technology fields such as aerospace and automotive because of the combination of excellent mechanical performance and lightweight. For these characteristics, classical metal alloys are progressive ...
The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...
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 ...
In metal matrix composites (MMCs) thermal stress relaxation can be achieved either by interface debonding, crack propagation or by dislocation motion. The present paper shows that in the case of magnesium matrix, interface thermal stresses are relaxed by d ...
In the pressure infiltration of metal matrix composites, molten metal is injected under external pressure into a porous preform of the reinforcing material. Equilibrium capillary parameters characterizing wetting for this process are summarized in plots of ...
Damping is an important parameter for vibration control, noise reduction, fatigue endurance or impact resistance of composite materials. In this study, a micromechanical model was used to predict the damping of a composite material containing shear thicken ...
Bone is considered in two different composite mechanics frameworks: first as an organic inorganic two phase composite, and second as a fluid-saturated porous solid. Experimental data from previous studies, in which the mechanical responses of bone or colla ...
Magnesium matrix composites made of pure (99.98%) magnesium reinforced with long carbon (Mg/C) and stainless steel (Mg/steel) fibers were processed by low pressure infiltration method. Mg/C composites were then oriented from the crystallographic point of v ...
