Mathematıcal Investıgatıon of Long-Term Strength Issues of Cylındrıcal Rods Made of Herıtage-Type Damageable Materıals Durıng Torsıon

The problem of dispersed failure of isotropic and cylindrical-anisotropic rods made of damageable materials during torsion has been investigated. Non-linear differential equations have been formulated, representing the expansion of dispersion front during torsion of rod transmitting power under a constant torque. For the development of dispersed failure process, formulas have been obtained to identify incubation period and, the problem has been resolved.
