Crack growth resistance of alumina, zirconia and zirconia toughened alumina ceramics for joint prostheses.
Mono-phase bio-ceramics (alumina and zirconia) are widely used as femoral heads in total hip replacements (THR) as an alternative to metal devices. Unfortunately, the orthopaedic community reports significant in-vivo failures. Material scientists are already familiar with composites like alumina zirconia. Since both are biocompatible, this could prove to be a new approach to implants. This pape...
متن کاملFatigue crack growth in ferroelectric ceramics below the coercive field
Perovskite-type ferroelectric ceramics have found many applications in actuators, sensors and memories. One critical limitation on their performance is due to electric fatigue, which refers to the deterioration of material properties associated with electric cycling. The degradation of electrical properties in ferroelectrics, which appears in the hysteresis loop in the form of a decrease of rem...
متن کاملMultiscale behavior of crack initiation and growth in piezoelectric ceramics
The multiscale nature of cracking in ferroelectric ceramics is explored in relation to the crack growth enhancement and retardation behavior when the direction of applied electric ®eld is reversed with reference to that of poling. An a priori knowledge of the prevailing fracture behavior is invoked for the energy dissipated in exchange of the macroand micro-crack surface. To avoid the formalism...

Thus, in addition to regular slip, mechanisms for ambient temperature The cyclic fatigue behavior of reactive hot-pressed Ti3SiCz plastic deformation in Ti3SiCz are thought to involve the ceramics are examined at temperatures from ambient to 1200°C readjustment of local stress and strain fields from kink band with the objective of characteriz...
متن کاملRandom Growth of Crack with R-curve: Markov Process Model
A probabilistic model for the randomness of the progressive crack growth in a quasi-brittle material such as concrete is presented. The model consists of a Markov chain adapted to R-curve behavior. It yields the crack propagation probability in any loading step as well as the probability of failure at any stage of the fracture process. The R-curve is obtained from the given test data on the eff...
