Slow strain rate tensile test
Slow strain rate testing (SSRT), also called constant extension rate tensile testing (CERT), is a popular test used by research scientists to study stress corrosion cracking. It involves a slow (compared to conventional tensile tests) dynamic strain applied at a constant extension rate in the environment of interest. … Visa mer The important characteristic of these tests is that the strain rate is low, for example extension rates selected in the range from 10 to 10 s . The selection of the strain rate is very important because the susceptibility to … Visa mer Electrode potential and other environmental factors such as temperature, pH and degree of aeration can greatly impact … Visa mer The evaluated parameters are: • time to specimen failure (e.g., breakage, or from other "failure" criteria) • ductility (by elongation to fracture or the reduction of the area) • ultimate tensile strength (from the maximum load) Visa mer WebbThe ARB processed specimens after tensile test, conducted at three different temperatures (523, 573, and 623 K) with two strain rates of (a) 0.1s-1and (b) -0.01s1, is shown in Figure 3. This figure indicates the effect of temperature and strain rate on elongation to …
