Opening-Function Simulation of the Three-Dimensional Nonstationary Interaction of Cracks in an Elastic Body

摘要: Integral relations between three-dimensional dynamic displacements (stresses) in an infinite elastic body with arbitrarily located plane cracks and discontinuities the of opposite crack faces are presented. The influence opening on each other is considered problem loaded by pulse forces. This reduced to a system boundary integral equations wave-potential type time domain. mode I stress intensity factors determined for two coplanar elliptic under forces form Heaviside function
