Finite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress corrosion cracking (SCC). Flat and U-shaped edge-notched specimens were investigated in terms of the CPF-induced stress in the metallic substrate and the stress in the CPF. For a U-shaped edge-notched specimen, the stress field in front of the notch tip is affected by the Young's modulus of th...

Damage and fracture mechanisms of two 2198 Al-Li thin sheet alloys having different thicknesses (2 and 6 mm) are investigated. Two heat treatments are studied: T3 and T8. Mechanical tests are carried out on flat specimens including smooth tensile samples and U-notched specimens (with various notch radii). Test data are used to identify the parameters of constitutive equations describing plastic...

The present paper is concerned with modelling damage and fracture in notched woven fabric composites. Previous experimental work has shown that, under tensile loading, damage at a notch in a variety of GFRP and CFRP composites based on woven fabric reinforcement comprises matrix damage and fibre tow fracture along the plane of maximum stress. It is these experimental observations that inform th...

The measurement of thin-layer mechanical properties, like compounds generated by thermo-chemical nitriding process, is a key issue to optimize and predict the endurance surface treatment against contact fatigue wear. An original FIB micro-tensile test strategy involving plain micro-notched tensile specimens proposed. These were machined in thin ε(50%)- γ’(50%) compound layer resulting from comm...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

High strengthened steel bar with elongated pearlite was prepared by caliber rolling at room temperature and its hydrogen embrittlement studied. A 0.6%C - 2%Si 0.2%Mn 1%Cr (in mass%) rolled to a reduction of area 88%, resulting in the evolution lamellar structure similar those cold drawn pearlitic steel. Mean spacing 70 nm texture consisted strong fiber direction parallel <110>. The exhibited hi...

generally, fatigue failure in an element happens at the notch on a surface where the stress level rises because of the stress concentration effect. the present paper investigates the effect of a notch on the fatigue life of the hsla100 (­high strength low alloy) steel which is widely applicable in the marine industry. tensile test was conducted on specimens and mechanical properties were obtain...

This paper presents a summary of the tests performed within a VAMAS (Versailles Project on Advanced Materials and Standards) round robin to examine the measurement of mode II interlaminar fracture toughness using four different test methods based on: End Notched Flexure (ENF), Stabilised End Notched Flexure (SENF), End Loaded Split (ELS), and four point End Notched Flexure (4ENF) carbon fibre r...
