The high temperature design codes of the ASME Section Ⅲ subsection NH and French RCC-MR have been compared in terms of a creep-fatigue damage evaluation for a component with weldments. Comparisons have been made for the three materials of Mod.9Cr-1Mo steel, 316L stainless steel and Alloy 800H that are included in b

damage given by dD/dN = g(D)f(Φ) were studied. Thin-walled graphite/epoxy tubes consisting of four of [±45]s laminates were used for the experimental study of sequence effects and the effects of mean stress on fatigue life. It was found that the sequence effects in two step uniaxial fatigue for [±45]s graphite/epox

To examine the effects of BCAA administration on fatigue substances (serotonin, ammonia and lactate), muscle damage substances (CK and LDH) and energy metabolism substances (FFA and glucose) after endurance exercise. Subjects (n = 26, college-aged males) were randomly divided into an experimental (n = 13, E

Infrared (IR) thermography nondestructive evaluation (NDE) technique was used for the monitoring of high-cycle fatigue damage in ceramic matrix composites (CMCs). The CMCs system was Nicalon fiber reinforced calcium aluminosilicate (CAS) glass-ceramic matrix composites designated as Nicalon/CAS. During fatigue

fatigue, cracks in wheels, cracks in rails and wheel-rail profile wear. This paper presents the applicability of electro-magnetic technique to the detection and sizing of defects in wheel and rail specimen. Under the condition of continuous rolling contact fatigue the damage of wheel has continuously monitored using t

This paper documents the findings from the study of fatigue cracking mechanisms in asphalt pavements using the finite element program (VECD-FEP++) that employs the viscoelastic continuum damage model for the asphalt layer and a nonlinear elastic model for unbound layers. Both bottom-up and top-down cracks are investig

Generally, load conditions of machine or structure in fatigue destruction is occurred not under single load conditions but under mixed load conditions. However, the experiment under mixing mode is insufficient because of no having test standard to the behavior of crack under mixing mode and variety of test methods, an

Therefore, it is necessary to investigate systematically the growth behavior of transverse crack for rail steel under mixed mode. In this study, the fatigue crack growth behavior of the trans

Finite element simulation of elastic wave propagation in a concrete plate was carried out to investigate its modeling and damage detection procedures. For the numerical stability three criteria were introduced and tested. With a proper element size and time increment, two different kinds or damage scenarios (crack and
