FRACTURE MECHANISMS AND LIFE ASSESSMENT UNDER HIGH‐STRAIN BIAXIAL CYCLIC LOADING OF TYPE 304 STAINLESS STEEL
— In order to investigate the elevated-temperature low-cycle fatigue characteristics of Type 304 stainless steel under biaxial loading, strain-controlled push-pull and torsional fatigue tests were… Expand

Continuous Observation of Cavity Growth and Coalescence by Creep-Fatigue Tests in SEM
Structural components operating at high temperatures in power plants are subjected to interaction of thermal fatigue and creep which results in creep-fatigue damage. In evaluating the life of those… Expand

THERMAL‐MECHANICAL LOW‐CYCLE FATIGUE UNDER CREEP‐FATIGUE INTERACTION ON TYPE 304 STAINLESS STEELS
— In this study, in-phase and out-of-phase thermal fatigue tests at the temperature ranges of 473–823 and 573–873 K were carried out on three kinds of 304 stainless steel as well as isothermal… Expand

High-temperature low cycle fatigue crack propagation and life laws of smooth specimens derived from the crack propagation laws
The objectives of this work are (1) to make clear the behavior of high-temperature low-cycle fatigue (LCF) crack propagation, (2) to verify the applicability of the J-integral to the fracture… Expand

Evaluation of Crack Initiation and Propagation Lives from Internal Defects and Lower Limit of Failure Life in High Temperature Fatigue on Ni-Based Single Crystal Superalloy
High temperature fatigue life assessment is one of the important issues in Ni-based superalloys for a gas turbine blade. Generally speaking, however, a superalloy with higher strength has larger… Expand

A Study on the Mechanics of Creep Crack Initiation and Propagation
A study of the mechanics of creep fracture of metals and alloys was carried out on the basis of the following assumptions. (1) The nucleation rate of a microcrack and the rate of creep crack… Expand

Creep Damage Detection for a Steam Turbine Rotor Material after Long-Term Service Using Ultrasonic Technique
The present paper describes an experimental study on a physical meaning of nondestructive creep damage detection for a steam turbine rotor material after long-term service using an ultrasonic… Expand

Effect of small-scale creep on crack initiation and propagation under cyclic loading
Small-scale creep (SSC) repeated under cyclic loading was found experimentally to accelerate crack initiation and propagation because of insufficient stress relief near a notch root or a crack tip in… Expand
