What methods can take account of strain rate effect?

methods which can take account of strain rate effect. Usually the effect of strain rate on the flow stress of metals is not significant at low temperature and becomes significant as the temperature rises. When the strain rate effect is significant, the forming pressure is lowered by decreasing the strain rate.See all results for this questionWhat is the effect of strain rate on flow stress?Usually the effect of strain rate on the flow stress of metals is not significant at low temperature and becomes. significant as the temperature rises.

The equivalence of strain rate and temperature can be demonstrated by performing this simple exercise.The Effects of Temperature | Plastics TechnologyThis lack of a predictable and repeatable structure gives rise to a situation where changes in temperature always influence the mechanical properties of these materials. This phenomenon can be captured by performing mechanical tests at various temperatures on any given material. One of the simplest ways to capture the load-bearing properties of a material over a wide range of temperatures involves a method known as dynamic mechSee more on ptonline effects of cold temperature and strain rate on the

How Cold Weather Affects Your Heart & Circulatory System

Oct 29, 2014 · Cold weather also puts immense strain on the heart. Low temperatures cause your blood vessels and arteries to narrow, restricting blood flow and reducing oxygen to the heart. Your heart must pump harder to circulate blood through the constricted blood vessels.
