There is experimental evidence pointing to the tendency of a straight crack to deviate from its plane even under strict Mode I loading. This experimental observation cannot be explained by the theoretical results obtained by N. V. Banichuk and by B. Cotterell and J. R. Rice. This paper attempts to explain theoretically the observed behavior. The conditions necessary for a slight deviation from straightness of a crack in the presence of an in-plane stress and under mixed-mode loading are derived, the deviation occurring with a finite initial slope (crack kinking) or without it (crack curving). The influence of the in-plane stress on the stability of the crack growth is also examined.
