Mixed-mode Fracture Analyses of Plastically- Deforming Adhesive Joints
A mode-dependent embedded-process-zone (EPZ) model has been developed and used to simulate the mixed-mode fracture of plastically deforming adhesive joints. Mode-I and mode-II fracture parameters obtained from previous work have been combined with a mixed-mode failure criterion to provide quantitative predictions of the deformation and fracture of mixed-mode geometries. These numerical calculat...
متن کاملElastic-plastic Mode-ii Fracture of Adhesive Joints
A numerical study of the elastic-plastic mode-II fracture of adhesive joints is presented in this paper. A traction-separation law was used to simulate the mode-II interfacial fracture of adhesively-bonded end-notched flexure (E.N.F.) specimens loaded in three-point bending, with extensive plastic deformation accompanying failure. The fracture parameters for the traction-separation law were det...
متن کاملThe mixed mode fracture mechanics in a hole plate bonded with two dissimilar plane
In the present research, the mixed-mode fracture mechanics analysis in a plate with central hole under tensile loading is considered. It is assumed that a plate containing two symmetrical hole-edge cracks is bonded with two dissimilar planes. The stress intensity factors at the crack tips are calculated. The problem is modeled in Casca software and this model is analyzed with Franc software. Th...
متن کاملNURBS-Based Isogeometric Analysis Method Application to Mixed-Mode Computational Fracture Mechanics
An interaction integral method for evaluating mixed-mode stress intensity factors (SIFs) for two dimensional crack problems using NURBS-based isogeometric analysis method is investigated. The interaction integral method is based on the path independent J-integral. By introducing a known auxiliary field solution, the mixed-mode SIFs are calculated simultaneously. Among features of B-spline basis...
متن کاملMixed Mode Fracture Toughness of an Adhesive Bonded Joint
Adhesive joints are continuously emerging as candidate to replace traditional fastening systems, such as riveting or welding, in primary structural applications. A wide class of components belonging to electronic, automotive and aerospace industries contains adhesive joints, however, the reliability during service constitutes a major technical problem as these contain flaws. Therefore, their us...
