R-Curve and fatigue crack growth behavior in partially stabilized zirconia
Nihon Kikai Gakkai ronbunshu, 2014 It has been known that the high fracture toughness of partially stabilized zirconia (PSZ) is due to a process zone caused by stress induced transformation at a crack tip.

New Nonlinear Cumulative Fatigue Damage Model Based on Ecological Quality Dissipation of Materials
International Journal of Aerospace Engineering, 2021 The failure of many aircraft structures and materials is caused by the accumulation of fatigue damage under variable-amplitude cyclic loading wherein the damage evolution of materials is complicated.

Arthritis Care &Research, EarlyView.Objective Frailty occurs prematurely in rheumatoid arthritis (RA) and is associated with poor health outcomes. We compared the performance of four frailty instruments, including a pragmatic alternative measure using chair sit‐to‐stand (STS), and evaluated their abilities to predict poor health outcomes.

Cyclic plasticity and fatigue of metals [PDF]
Le Journal de Physique IV, 1993 This report is a survey of the cyclic deformation and fatigue behaviour of selected engineering steels and alloys. Emphasis is placed on the important roles of the cyclic slip mode and the stability of the microstructure during cyclic stressing and on the conditions of fatigue testing with respect to the failure mechanisms and fatigue life.

Arthritis Care &Research, EarlyView.Objective To support high‐quality, patient‐centered care for systemic lupus erythematosus (SLE), the American College of Rheumatology (ACR) developed evidence‐based measures incorporating clinical and patient‐reported outcome measures (PROMs). Using the Consolidated Framework for Implementation Research (CFIR), we conducted semistructured interviews ...

Associations of Rheumatoid Arthritis Disease Activity With Frailty Over Five Years of Follow‐up
Arthritis Care &Research, EarlyView.Objective To evaluate whether rheumatoid arthritis (RA) disease activity is associated with frailty both in cross‐section and longitudinally. Methods Participants within the Veterans Affairs Rheumatoid Arthritis (VARA) registry enrolled from 2003 to 2022 were included.
