Two Parameter Fracture Mechanics: Fatigue Crack Behavior under Mixed Mode Conditions
Original language description
The fatigue crack path has been studied on tensile specimen with holes. The experimental crack path trajectories were compared with those calculated numerically. To incorporate the influence of constraint on the crack curving, we predicted the fatigue crack path by using the two-parameter modification of the maximum tensile stress (MTS) criterion. The values of the mixed-mode stress intensity factors KI, and KII as well as the corresponding constraint level characterized by T-stress were calculated forthe obtained curvilinear and the reference crack path trajectories. It is shown that in the studied configuration the effect of T-stress on the crack path is not significant. On the other hand the effect of constraint on the fatigue crack propagation rate is more pronounced.

Dvouparametrová lomová mechanika: chování únavové trhliny při kombinovaném namáhání
Czech description
Chování únavové trhliny je studováno na taženém vzorku se dvěma otvory. Experimentálně změřená dráha trhliny je porovnána s numericky predikovanou. Pro stanovení dráhy numericky simulované trhliny je použito MTS kritérium a jeho dvouparametrová modifikace. Je ukázáno, že v tomto případě nemá T-napětí zásadní vliv na dráhu šíření trhliny. Na druhou stranu má constraint efekt podstatný vliv na rychlost šíření únavové trhliny.
