Effect of 2wt% Cu addition on tensile properties and fracture behavior of Al-6Si-0.5Mg-2Ni alloy at various strain rates were studied. The solution treated Al-6Si-0.5Mg-2Ni (-2Cu) alloys, were aged isochronally for 1 hour at temperatures up to 300C. The uniaxial tension test was carried out at strain rate ranging from 10s to 10s in order to investigate the strain rate dependence of tensile prop...

Thin films of were prepared by casting and its tensile properties like tensile strength (TS) and elongation at break (Eb%) were studied. The gelatin films were procured with two types of monomers such as 5% ethylene glycol (EG) and 5% ethylene glycol dimethacrylate (EGDMA) to increase the tensile properties. Five percent of monomer solutions were prepared in MeOH along with 2% photoinitiator; I...

Biodegradable polyesters allow the development of acceptable bio-composites and bio-blends from agricultural-based raw materials without impairing their biodegradability and other useful properties. The tensile properties of binary blends of polystyrene (PS) with the biodegradable polyesters polycaprolactone (PCL), D,L-polylactic acid (PLA), and Eastar Bio Ultra (EBU) were investigated. Blend c...

The goal of the study, is to specify mechanical properties of epoxy and acrylic-based adhesives commonly used for bonding of metal connections. For this reason, the bulk specimens, manufactured from Devcon A and Akfix-E300 as epoxy material, Erde GTR and Erde GTS as acrylic based adhesive material, were cast in accordance with the test standards. The mechanical properties of the specimens obtai...

polyvinyl ester green composites were synthesized with walnut shell powder (wsp) by in-situ polymerization technique. the green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...

stress relieving is a common practice among manufacturing codes for reducing the magnitude ofresidual stresses in welded, quenched, and tempered steel structures and pressure vessels. the presentwork investigates the effect of stress relieving at 480, 560, 620, and 680°c on the microstructure andmechanical properties of 20 mm astm a517 gr. b steel plate weldments produced by shielded metal arcw...

Rocks are less resistant to tension than compression or shear. Tension cracks commonly initiate shear failure. The mechanical behavior of layered rocks under has been studied extensively, whereas the tensile still remains uncertain. In this paper, we study effect layer orientation on strength and failure patterns direct indirect through experimental numerical testing (RFPA2D: software Rock Fail...

Amorphous Fe73B7Si16Nb3Cu1 ribbon was crystallized rapidly by electric current heating under simultaneously applied tensile stress along the ribbon axis. As a result, strong transverse magnetic anisotropy was induced in the ribbon. Dynamic magnetic properties of the ribbons rapidly heated either under the tensile stress or without tensile stress were measured using toroidal cores. Optimal elect...
