The valve was instrumented, and measurements were taken to record the strains and deflections during the test. The paper describes the salient features of the test setup, details of testing, and results...

...RL Plaut; CM Sellars High strain rate hot tension tests have been carried out on AISI 1020 (Unified Numbering System [UNS] G10200) steel using a Gleeble® testing machine. Tests have been terminated at a series of strains and the specimen geometries measured. From these measurements, local areas...

..., an internally pressurized cylinder specimen was designed for use in a hydraulically actuated (MTS) testing machine. Biaxial cylinder fabrication and appropriate testing procedures were developed. Stress-strain and strength characteristics were determined for various fabric material types and material lots...

...AK Shoemaker; RR Seeley A task group designated ASTM E24.01.06 conducted round robin tests to estabish guidelines for preparing a test specification for rapid-loading plane-strain fracture-toughness testing, K Ic( ) (the time of the test from zero to maximum load, in milliseconds, is included...

...UC Jindal; ML Mandal Scientific and technical literature is full of research papers on the investigations of stress concentrations around holes and rows of holes in plates. All these stress concentrations have been determined in specimens where the stresses and strains away from the holes are well...

The testing program included (a) low-cycle tests under fully reversed total-strain control and (b) high-cycle tests under fully reversed stress control. The latter tests were performed in a stress sequence of the staircase...

A conventional blunting...

...PB Crosley; EJ Ripling A test method is described for measuring plane strain crack arrest toughness K I a with a compact shaped specimen. The method has a number of advantages over those previously used. Rather than a fatigue crack for initiation, a machine-notched, brittle weld is used, which...

The scalar quantity temperature can be used in stress analysis to determine other scalar quantities related to stress or both stress and plastic strain. Three methods are proposed for analyzing temperature...
