Analysis of stress singularity in adhesive joints using meshless methods

Recent years saw a rise in the application of bonding techniques engineering industry. This fact is due to various advantages this technique when compared traditional joining methods, such as riveting or bolting. The growth methods demands faster and more powerful tools analyze behavior products. For that reason, adhesive joints have been subject intensive investigation over past few years. Recently, fracture mechanics based approach emerged with great potential evaluate joint behavior, called Intesity Singular Stress Fields (ISSF), similar Intensity Factor (SIF) concept. However, it allows study multi-material corners does not require an initial crack. was yet tested meshless methods. present work intends fill gap, resorting Radial Point Interpolation Method (RPIM). With purpose, four different overlap lengths (LO) bonded brittle were studied. interface corner's stresses also evaluated. predicted strengths experimental data assess accuracy applied In conclusion, ISSF criterion proved be applicable namely RPIM.
