Matrix cracking of fiber-reinforced ceramic composites in shear
The mechanics of cracking in fiber-reinforced ceramic matrix composites (CMCs) under general loadings remains incomplete. The present paper addresses one outstanding aspect of this problem: the development of matrix cracks in unidirectional plies under shear loading. To this end, we develop a model based on potential energy differences upstream and downstream of a fully bridged steady-state mat...
متن کاملEffects of non-uniform strains on tensile fracture of fiber-reinforced ceramic composites
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 sharing conditions to predict fracture in three model problems in which non-uniform strains occur: (i) an end-constrained plate subject to a linear...
متن کاملTensile and Flexure Strength of Unidirectional Fiber-Reinforced Composites: Direct Numerical Simulations and Analytic Models
A Local Load Sharing (LLS) model recently developed by Curtin and co-workers for the numerical simulation of tensile stress-strain behavior in fiber-reinforced composites is used to predict the tensile strength of metal matrix composites consisting of a Titanium matrix and unidirectionally aligned SiC fibers. This model is extended to include the effects of free boundary conditions and non-cons...
متن کاملThermal resistance of bridged cracks in fiber-reinforced ceramic composites
The thermal resistance of a bridged matrix crack in a fiber-reinforced ceramic composite is analyzed. The problem is cast in terms of a unit cell comprising an infinitely long composite cylinder with a single matrix crack perpendicular to the fiber axis. At the outset, it is demonstrated that the thermal resistance of such a crack can be represented by a simple circuit consisting of two paralle...
متن کاملAnomaly Detection and Microstructure Characterization in Fiber Reinforced Ceramic Matrix Composites
ANOMALY DETECTION AND MICROSTRUCTURE CHARACTERIZATION IN FIBER REINFORCED CERAMIC MATRIX COMPOSITES Name: Bricker, Stephen E. University of Dayton Advisor: Dr. Russell Hardie Ceramic matrix composites (CMCs) have the potential to replace current superalloys being used in hot components of jet engines. CMCs with continuous fiber reinforcement exhibit significant strength retention beyond tempera...
