Abstract: Failure criteria for a wide range of situations where the main consideration is flow or fracture are reviewed. Some of the concepts are well known and in wide use while others are of ...

Abstract: A rational approach to cutoff wheel selection is presented based on the most important criterion for this operation—minimum cost per cut. New parameters are identified which play a more significant ...

Abstract: A hydrostatic stress modified maximum tensile strain theory of fracture previously shown to be in good agreement with results on tungsten carbide specimens loaded to fracture under a variety ...

Abstract: Attritious wear of silicon carbide in simulated grinding tests against a cobalt base superalloy at high speed and extremely small feed rate was studied using a scanning electron microscope (SEM) ...

Abstract: Rubber is an amorphous elastomer of high entropy that is normally treated by statistical thermodynamics instead of molecular modeling. A pseudo-amorphous model is introduced that is useful in ...

Abstract: Tools which provide controlled contact on the tool face are used to study the action of free machining steels. The mean normal stress on the tool face σc is found to increase with increased ...

Abstract: A phenomenon called the “pinch-off effect” discovered by P. W. Bridgman about seventy five years ago that constituted a mode of failure in his high pressure equipment may be used to advantage ...

Abstract: In any grinding operation heat flows periodically into the abrasive grains in the surface of the wheel during wheel-work contact and is extracted during the remaining portion of a single ...
