Examination of the Failure of Sandwich Beams with Core Junctions Subjected to Transverse Shear Loading

摘要

The article concerns failure and fatigue phenomena associated with local effects occurring in the vicinity of junctions between different core materials in sandwich beams subjected to transverse shear loading. It is known from analytical and numerical modeling that these effects lead to stress concentrations at such junctions. However, their influence on the failure behavior is not fully understood, and there are indications that the available models overestimate the importance of the local effects.
