Abstract EN
The interaction between a macrocrack and a cluster of microcracks has been investigated based on Muskhelishvili’s complex potential method.
A step-by-step subproblem procedure is used to satisfy the stress boundary conditions on each crack surface.
The interactions between a cluster of microcracks and a macrocrack and the interaction among microcracks are analyzed.
Three damage configurations as chained, reverse-chained, and randomly distributed microcracks have been designed to simulate the damage around the macrocrack tip.
The solution of an infinite elastic plane containing a macrocrack and a cluster of microcracks is presented for the plane subjected to a uniform tensile load.
The stress intensity factor (SIF) at the macrocrack tip and the microcrack tips is obtained.
The results show that the inclination angle of the microcrack and the distance between the macrocrack and microcracks have a great influence on SIF.
When the inclination angle is small, the SIF at microcrack tips may be larger than other inclination angles.
These results are helpful to analyze the fracture or damage behaviors of materials.
