Approximation of Heat Dissipation-Crack Rate Curve for Fatigue Crack in Stainless Steel

The experimental and theoretical analysis of thermodynamical peculiarities heat flux at the fatigue crack tip during its propagation was made in presented work. goal is to elucidate relation between flow kinetic for different loading conditions. plane specimens with notch from stainless steel (AISI 304) were studied. There two types uniaxial one type biaxial loading. A dissipation measured by simultaneous use contact noncontact techniques. samples subject cyclic constant stress amplitude coefficients. functional dependence received experiment measurement analytical calculation. This depends on only material righty all fracture mode.
