Interlaminar Fracture Characterization of a Carbon- Epoxy Composite in Pure Mode Ii
The interlaminar fracture toughness in pure mode II (GIIc) of a Carbon-Fibre Reinforced Plastic (CFRP) composite is characterized experimentally and numerically in this work, using the End-Notched Flexure (ENF) fracture characterization test. The value of GIIc was extracted by a new data reduction scheme avoiding the crack length measurement, named Compliance-Based Beam Method (CBBM). This meth...
متن کاملInterlaminar Mode II Fracture Characterization
Delamination is an important concern in the context of structural behaviour of laminated composite materials. It is known that delamination can diminish the stiffness and the strength of the material and promote structural failure. Delamination onset and growth is governed by interlaminar fracture toughness of the material. Delamination propagation is frequently dominated by mode II fracture; c...
متن کاملThe Fracture Behaviour of Adhesively-Bonded Composite Joints: Effects of Rate of Test and Mode of Loading
The present paper discusses the results of an investigation into the effects of test rate and the mode of loading on the fracture energy, Gc, of adhesively-bonded fibre-composite joints. Various carbon-fibre reinforced-polymer (CFRP) matrix composite substrates have been bonded using two different types of automotive structural epoxy-adhesives. They have been tested via loading the bonded joint...
متن کاملMode Ii Fracture Behavior of Bonded Viscoelastic Thermal Compressed Wood
The influence of viscoelastic thermal compression (VTC) of wood on bonding performance was studied. Mode-II (shear mode) fracture of the bonded interphase was performed using the overnotched and end-notched flexure methods. The study examined four groups of specimens; a control and VTC specimens with three different degrees of densification (63, 98, and 132%). The specimens were bonded with phe...
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...
