WebSep 16, 2024 · Elastic slow dynamics, consisting in a reversible softening of materials when an external strain is applied, was experimentally observed in polycrystalline metals and presents analogies with the same phenomenon more widely observed in consolidated granular media. Since the effect is extremely small in metals, precise experimental … WebThe dissipation of energy by elastic hysteresis was determined by the fall of temperature between the middle point of the bar and the ends. It could be measured accurately in this way when the range of stress was near the elastic limit (25 tons per square inch) and could be detected when the range was 10 tons per square inch. WebElastic hysteresis occurs whenever a plastic (inelastic) deformation occurs. A plastic deformation results from the displacement of defects, such the dislocations that are always present in real materials.
