Interaction of two coplanar penny-shaped cracks with transient elastic waves

摘要

The three-dimensional elastodynamic response of two coplanar penny-shaped cracks embeedded in an infinite elastic solid subjected to transient elastic waves is investigated. A time-domain boundary integral equation method is used for calculating the time dependent crack opening displacements and subsequently the dynamic stress intensity factors. Numerical computations are carried out for various incident transient longitudinal and transverse waves.
