Stress singularity analysis of bodies with a bi-material notch

Abstract eng:
The article deals with analysis of a stress state in the case of constructions with a bi-material notch. The eigenvalues λ as well as the stress singularity exponents are determined and discussed for three specific geometries of a bi-material notch and for varying material combinations. The values λ are presented in dependence on the composite parameters α, β in so called Dundurs’ parallelograms. A numerical example of critical stress estimation is given at the end of the article.
