... Abstract It has been shown that the degree of fatigue life reduction due to the pressurized water reactor environment depends on strain rate. It was reported that there was an insensitive strain zone, at which the strain rate had little influence on the fatigue life. The insensitive strain zone...

... Abstract In this study, Johnson-Cook fracture strain model considering the effect of stress triaxiality and strain rate is determined for austenitic stainless steel 304. Tensile test data of four different stress triaxiality and six different strain rate conditions are used to determine...

... Abstract In this paper, a strain-based failure assessment is performed on a canister made of stainless steel when a spent nuclear fuel dry storage system goes through a drop accident, to investigate the effects of strain rate on strain-based failure assessment results. The KORAD-21 multi...

... of F en , Revision 0 of NUREG/CR-6909 [1] permits temperature averaging for the case of a constant strain rate and linear temperature response, and permits it in other cases as well, but only if the average temperature used produces results that are consistent with the modified rate approach [1, p. A.5...

... Uni-axial fatigue tests up to 10 9 cycles were conducted at two cyclic frequencies (10 and 250 Hz) under several stress ratios ( R = −1, 0.1, and 0.5) to investigate the effects of strain rate on the very high cycle fatigue properties of SFVQ1A, which is equivalent to ASTM A508 Cl.3. Longer...

... The primary objective of the present paper is to depict the mechanical behavior of high density polyethylene, HDPE, pipes to provide the designer with reliable design data relevant to practical applications. Therefore, it is necessary to study the effect of strain rate and specimen configuration...

... under a specified strain rate. Plastic deformation in the process will lead to martensite transformation and may influence material’s strength and ductility. Cold stretching tests of EN 1.4301 stainless steel are carried out at different quasi-static strain rates of 10 −3 and 10 −5 /s, following...

...) for the occurrence of SCC were determined. An important R&D program is in progress to develop initiation and propagation models for SCC of austenitic SS in primary environment. 304L pre-strain strain rate stress corrosion cracking PVP-Vol. 490, Storage Tank Integrity and Materials Evaluation July 25...
