Analysis of Stress Singularity on Adhensively Bonded Interfaces in the Dissimilar Materials by BEM
초록
영어
Adhensively bonded joints in dissimilar materials have been widely applied in various engineering fields such as automobiles, space vehicle, semiconductor, vessel. To establish a fracture criterion and a reasonable strength evaluation method on adhensively interfaces in dissimilar materials, it is necessary to assess fracture parameters with various bonding conditions. In this paper, through stress analysis by using the 2-dimensional elastic boundary element method(BEM), the stress singularity factors on adhensively bonded joint in dissimilar materials were investigated quantitatively, and suggested the strength evaluation method by using fracture parameters
