A crack detection (CD) paint was applied to weld lines of a transverse rib welded joint specimen of a rolled steel for welded structures, and the effects of the paint on visual detection of fatigue cracks were evaluated by performing a fatigue test. Remarkable color development was observed in the CD paint when fatigue cracks propagated along the weld toe lines. At intervals in the fatigue test...
Background & Aim: Many patients with cancer suffer from fatigue, which may be related to their disease or treatment process. Fatigue aggravates the condition and increases the burden of the disease. Acupressure can be effective as a complementary method for patients' fatigue. Therefore, this study was conducted to determine the effect of acupressure on the SP6 point on fatigue in the patients w...
This research comprises a study of the effect of heat treatment on fatigue behavior of (A193-51T-B7) alloy steel. Two heat treatment processes were conducted, namely, annealing and quenching followed by tempering at 200C. All fatigue tests were carried out using a rotary bending machine with constant stress ratio, R=-1. The eddy current probe was used to measure the crack length propagation. Fr...
To solve the problem of rutting and fatigue damage to asphalt pavement, rutting and fatigue performances of Qingchuan rock asphalt modified asphalt were studied, based on the dynamic shear rheometer test, the dynamic creep test, the rutting test, the indirect tensile fatigue test, the small-sized acceleration loading test, the compressive resilient modulus test, the BISAR3.0 Program and the rut...
Purpose: Reaction time is a good indicator of coordination between sensory motion and individual performance. It is the time interval from perceiving sudden stimulus until the reaction to that stimulus. One of the factors affecting reaction time is fatigue. Considering the different characteristics of fatigue in men and women, this study aimed to compare the effect of fatigue on the choice reac...
