✦ Synopsis

The objective of this paper is to investigate the fracture behavior of short fiber reinforced ceramic structures by means of the fracture mechanics approach. In this paper, structural stability in relation to crack growth in shear key structures with a softening process zone under effectively bending loads is studied through residual strength diagrams and load deflection curves. In addition, the behavior of process zone size preceding traction free crack in the shear key structure is investigated.

Shear key structures with a softening process zone can behave stably under loading in the presence of a crack. Results of this analytical study potentially indicate that short fiber reinforcement for ceramics could eliminate catastrophic failure or unstable fracture behavior of ceramic structures, and also indicate the plausible applicability of ceramics as construction materials.
