Abstract

In this paper, finite element (FE) analysis is performed for the asymmetric four-point bend specimen under mixed mode fracture loading conditions. This test configuration can be used in studies of mixed mode I/II and mixed mode I/II/III crack problems. In order to study mixed-mode I/II loading, two alternatives of changing the crack position and changing the support position are considered in FE analysis and the obtained results are compared. For mixed mode I/II/III loading, an important parameter, the proportion of stress intensity factors is studied for two cases, i.e. changing the inclined crack location and altering the crack inclination plane in two different directions. It is shown that for mixed-mode I/II, the results are more sensitive to changing the position of support than crack plane. For mixed-mode I/II/III changing the position of the inclined crack can generate a better variation of stress intensity factors than having the specimen with a crack of two inclination angles which is also difficult to fabricate.
