Effect of loading rate on the plane stress fracture toughness properties of an aluminum alloy
The effect of loading rate on the plane stress fracture toughness properties of a 3.2-mm thick 2219-T87 aluminum alloy plate was investigated with center-cracked panels. Plane-stress J-resistance curves were generated at a constant displacement rate of 10-6 and 5.7 m s-l. Dynamic fracture testing was performed with a coupled pressure plates technique. Fracture initiation and propagation toughne...
متن کاملApplication of the GTN Model in Ductile Fracture Prediction of 7075-T651 Aluminum Alloy
In this paper the capability of Gurson-Tvergaard-Needleman (GTN) model in the prediction of ductile damage in 7075-T651 aluminum alloy is investigated. For this purpose, three types of specimens were tested: Standard tensile bars, Round notched bar (RNB) specimens and compact tension (C(T)) specimens. Standard tensile bar tests were used to obtain the mechanical properties of the material and t...
متن کاملEffect of Processing on Inelastic Fracture Behavior of 6061 Aluminum
Statistical concepts from Design of Experiments were used to study the effect of thermal processing on the mechanical properties of 6061 aluminum. The soak temperature, cooling rate and soak temperature/cooling rate interaction term were found to be the most influential processing variables. Soak time and heating rate were statistically insignificant in the current experimental design, but modi...
متن کاملAnalysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061
Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
