An elastic-plastic analysis is performed for two problems relevant to fracture mechanics: a semi­ infinite body with an edge crack in a far out-of-plane shearing field and an infinite plate under plane stress conditions containing a finite line crack in a remote tensile field. Amplitudes of the dominant singularity in the plastic region at the crack tip, the plastic stress and strain intensity ...

The stress field at the tip of a crack of a thin plate of elastic material that is broken due to a mode III shear tearing has a universal form with a nonuniversal amplitude, known as the stress intensity factor, which depends on the crack length and the boundary conditions. We present in this paper exact analytic results for this stress intensity factor, thus enriching the small number of exact...

research on stress and stress perception has primarily focused on the acoustic characteristics of stressed versus unstressed syllables, and how listeners make use of acoustic cues to make judgements as regards the occurrence of stress. Most phoneticians agree that the three acoustic dimensions involved in the realisation of stress are duration, fundamental frequency, and intensity. These acoust...

Proposal and discussion two alternative residual applied definitions. Discussion face contact modelling calculation in fatigue load cycles. The correlation between (SIF) range growth a powerful tool fail-safe design approaches to lightweight structures. key...

Background: Hypertension induces cardiac hypertrophy. Oxidative stress plays an important role in the pathogenesis of hypertension induced cardiac hypertrophy. Exercise and Quercetin (as activators of Sirtuins) reduce oxidative stress. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) with Quercetin supplement on oxidative stress and level of concent...
