Notes:
The use of linear and second order stress extrapolation to obtain KI and KII intwo-dimensional finite element models of a thick plate containing an edge crack was examined. Threeloading cases were studied, including classical Mode I and Mode II problems and a problem oftribological contact. Linear extrapolation was observed to yield accurate predictions of KI in cases ofdominant Mode I loading. In Mode II situations, notably where the crack faces experiencedcompressive normal stresses, second order extrapolation was observed to improve estimates of KII
