Higher-powered electronics are being integrated into automobiles rapidly. With these electronics comes a problem of how to cool this equipment economically. Heatsink costs have not benefited nor adapted to the high volume nature of automotive electronics. Specially shaped heatsinks are much more efficient for a given size than aluminum extrusion-based ones, most prevalent used in automobiles. H...

The thermalmechanical safety analysis of a lowenriched uranium foil based annular target for molybdenum-99 production will be presented. The target constitutes a low enriched uranium foil sandwiched between two concentric aluminum tubes to form a composite cylindrical structure. A threestep numerical model is built using the commercial finite element code Abaqus FEA to simulate the assembly pro...

The application materials motorhomes will meet improving panels, such ...

Metal matrix composites with aluminum as base metal are extensively used in the important engineering industries, their properties can be improved for many requirements. In current work it is tried to make process cost effective. The efforts made less expensive properties. this a attempt fabricate Aluminum LM25 based Matrix Composite aim of developing low conventional method manufacturing Compo...

Aluminum alloy materials are very difficult to break in the processing process; chip accumulation leads poor stability. In this paper, a coated composite micro–textured tool is presented. The influence of on shape and cutting force under same parameters studied. Firstly, combination temperature optimized based test. Secondly, combined with finite element simulation technology, three kinds micro...

In this study, an approach to identify factors affecting on surface roughness in a machining process is presented. This study is based on 81 data about surface roughness over a wide range of cutting tools (conventional, cutting tool with holes, cutting tool with composite material), workpiece materials (AISI 1045 Steel, AA2024 aluminum alloy, A48-class30 gray cast iron), spindle speed (6301000 ...

BACKGROUND There have been numerous attempts to demonstrate the phenomenon of ion exchange between auto cure glass ionomer cements (GICs) and dentine. The purpose of this study was to employ an electron probe microanalysis (EPMA) technique to examine the interchange of elements between non-demineralized dentine and two types of restorative material, auto cure GICs and a resin composite. METHO...
