It became evident at the residual stress meeting in San Antonio last yearl that it is necessar2 to restate the definitions for internal stresses. In general, we are talking about three kinds of residual stresses as shown in Table I. The one that's called the first kind of internal stress ranges over millimeters or centimeters {or long range internal stress) and can be identified by x-rays throu...

The balance of forces in the sea ice model of Hibler [ 1979] is examined. The model predicts that internal stress gradients are an important force in much of the Arctic Ocean except in summer, when they are significant only off the northern coasts of Greenland and the Canadian Archipelago. A partition of the internal stress gradient between the pressure gradient and the viscous terms reveals th...

PURPOSE This study investigated the relationship among types of attribution tendencies, academic stress, coping efficacy, and academic adjustment in medical students and identified the means by which the academic adjustment of medical students can improve. METHODS Four hundred forty-two subjects from 2 medical schools in Korea were analyzed; 202 were male, 206 were female, and 34 did not iden...

In this study, the non-linear creep behaviour of a thick-walled cylinder made of stainless steel 316 is investigated using a semi-analytical method. The thick-walled cylinder is under a uniform internal pressure and a non-axisymmetric thermal field as a function of the radial and circumferential coordinates. For the high temperature and stress levels, creep phenomena play a major role in stress...

Since fuel must be injected with appropriate pressure and time for accurate performance of diesel engines, then proper function of engine is influenced by accurate function of injector pump. At first total pump was designed by SolidWorks 2012 software. Then the total relationship of rotor, roller, internal cam ring, pole shoe and plunger in injector pump in MF285 tractor and their performance w...
