Inherent Strain Based Theory of Measurement of Three Dimensional Residual Stress Distribution and Its Application to a Welded Joint in a Reactor Vessel
(The American Society of Mechanical Engineers (ASME), 2014)The stress that exists in a body under no external force is called the inherent stress. The strain that is the cause (source) of this stress is called the inherent strain. This study proposes a general theory of an ... -
Effect of Load Angle on Limit Load of Polyethylene Miter Pipe Bends 1
(The American Society of Mechanical Engineers (ASME), 2014)The aim of this paper is to investigate the effect of crack depth a/W = 0–0.4 and load angle (30 deg, 45 deg, and 60 deg) on the limit load of miter pipe bends (MPB) under outofplane bending moment with a ... -
Investigation of Bulging Behavior of Coke Drum: Feasible Study on Causes of Bulging
(The American Society of Mechanical Engineers (ASME), 2014)Coke drums undergo cyclic operations typically in the temperature range from ambient temperature to about 500 آ°C (930 آ°F). During quenching, the coke drum is inevitably subjected to a rapid drop in temperature because ... -
Experimental Investigation of Net Section Collapse Criterion for Circumferentially Cracked Cylinders Subjected to Torsional Moment
