Error sources and geometry effects in DCDC-tests

Schell, Günter; Rizzi, Gabriele; Hettich, Pascal; Zielonka, Paul; Wagner, Susanne; Fett, Theo

Abstract:
The main advantages of DCDC-specimens are the completely stable crack extension after spontaneous crack initiation due to the decreasing stress intensity factor with increasing crack length and a very high path stability due to the strongly negative T-stress term. In this report, several possible error sources occurring in DCDC-tests are
addressed: end effects in short specimens, differently long cracks at both sides of the drill hole, slight offset of the hole and the crack, non-symmetrical loading,
