Mixed 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...
متن کاملThe significance of crack-resistance curves to the mixed-mode fracture toughness of human cortical bone.
The majority of fracture mechanics studies on the toughness of bone have been performed under tensile loading. However, it has recently been shown that the toughness of human cortical bone in the transverse (breaking) orientation is actually much lower in shear (mode II) than in tension (mode I); a fact that is physiologically relevant as in vivo bone is invariably loaded multiaxially. Since bo...
متن کاملRefinements to the Mixed-Mode Bending Test for Delamination Toughness
The mixed-mode bending (MMB) test for delamination toughness was first introduced in 1988. This simple test is a combination of the standard Mode I (opening) test and a Mode II (sliding) test. This MMB test has become widely used in the United States and around the world for mixed-mode toughness measurements. Because of the widespread use of this test method, it is being considered for standard...
متن کاملPlastic Analysis of Mixed Mode Plane Stress Crack Problems
Two parameters are identified for characterizing the deformation in the plastic zone near the tip of a crack when mixed mode conditions prevail. Details of the near-tip stress and strain distributions are presented f or hardening materials in which a diffus e plastic zone occurs under plane stress conditions. For small scale yielding the two near-tip parameters are related to the two elastic s ...
متن کاملFinite Element Modeling of Crack Initiation Angle Under Mixed Mode (I/II) Fracture
Present study deals with the prediction of crack initiation angle for mixed mode (I/II) fracture using finite element techniques and J-Integral based approach. The FE code ANSYS is used to estimate the stress intensity factor numerically. The estimated values of SIF were incorporated into six different crack initiation angle criteria to predict the crack initiation angle. Single edge crack spec...
