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

The article considers the stress-strain state of an array of flat cracks. Within the framework of this work, a mathematical model is being developed that describes the process of crack opening for various geometric configurations. A calculation algorithm is proposed that makes it possible to determine the numerical characteristic of the stress-strain state by the boundary element method - 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.
