Abstract
Stresses near the free edges of the interface of bonded dissimilar materials can be described by the sum of a regular stress term and one or two stress singularity terms. A method for the calculation of the corresponding stress intensity factors from finite element results is presented which is useful to determine two stress intensity factors together. Results for some geometries show that all three terms may contribute significantly to the stress distribution near the free edge of the interface for thermal stress.
