Mathematical Modelling a Stress State of Inhomogeneous Band with External MacrodefectA.I. Nosacheva
Analytical and numerical methods are applied to examine the stress state of discrete inhomogeneous band with macrodefect. On this basis the algorithm of finding a critical tensile load is received and realized depending on the size and the defect arrangement, the tilt angle of contact surface and the coefficient of mechanical heterogeneity.
