Cracks under Mixed Mode loading:Questions and solutions for isotropic and graded materials
In reality cracks often initiate and grow due to mixed mode loading.This paper deals with questions about stable and unstable crack growth and the crack growth direction under multi-axial loading conditions.For homogeneous materials many criteria and experimental confirmations exist.This paper shows a selection of these solutions and some experimental investigations.In practice innovative manufacturing and application-oriented products considering lightweight construction gain increasingly in importance.In this context structures with graded material properties are produced.However there does not exist many concepts for these graded materials.Within this paper fracture and fatigue criteria and experimental findings are presented.In particular the TSSRB-concept is used for the determination of crack growth in fracture mechanical graded materials.
