Determination of the stress intensity coefficient of the first type of crack system

The article considers the stress-strain state of a system of plane cracks. Within the framework of this work, a mathematical model describing the process of crack opening for various geometries of mutual arrangement is being developed. A calculation algorithm is proposed that allows determining the numerical characteristic of the stress-strain state by the method of boundary elements - the stress intensity coefficient. The results reflecting the operability of the obtained mathematical model and allowing for further research in the field of fracture mechanics are presented.
