Crack Characteristics of Residual Stress Fields
Original language description
A finite element algorithm implemented in plane stress condition utilizing isoparametric elements may predict fatigue crack closure behaviour of fatigue cracks in residual stress fields, the finite element methodology in elastic-plastic formulation employing high order elements is established. The crack opening and closing characteristics via a compressive residual stress field is considered to be affected by the magnitude of applied load and the crack tip position. By dint of a compressive residual stress field, three variant types of crack opening behaviour, namely normal, unsymmetric partial and symmetric partial ones are studied. At the same time, the partial crack opening stress intensity factor inclusive of the opening effect is suggested to predict the fatigue crack propagation. The boundary element method of modelling crack propagation in the presence of residual stress fields is demonstrated.
