Modeling of fatigue crack growth in ceramics under compressive cycling

Original language description

This contribution presents a simple numerical model for crack growth under mode-I compressive fatigue loading. Residual tensile stress at the crack tip, which is responsible for crack advance, is simulated by the plastic-like behavior in compression. Tensile part of the constitutive law accomodates a phenomenological hysteresis behavior. This constitutive law is implemented into an implicit discrete 2D numerical model. The model is used to simulate the compression-compression fatigue fracturing of ceramics, particularly polycristalline alumina. It is shown that the model is capable of capituring trends observed in experimentally obtained crack growth behavior.
