Singular and non-singular stress terms for the failure assessment of bi-material notches
Original language description
Bi-material notches are frequently found in engineering structures or electronic components. The stress concentration in the vicinity of bi-material notch tip is often responsible for a crack initiation and thus for a failure of whole component. The conditions of failure for the cases of bi-material notches are usually evaluated using generalized fracture mechanics approaches based on singular stress terms only. This is due to the values of corresponding stress singularity exponents, which generally differ from 1/2 (those of a crack in homogeneous material). Even so, in some cases of geometrical or material combinations of bi-material notches the questions, which cannot be answered on the basis of the singular stress terms only, still remain. These specific questions are usually related to the cases of bi-material notches with only one singularity or to the cases where the singularity dominates only in a very small region around the stress concentrator tip. For this kind of cases, the
