Improvement of a Cycle J Integral for CT Specimens [PDF]
Journal of Engineering for Gas Turbines and Power, 1985 The cycle J integral formula for CT specimens has been improved as follows: ΔJ=(2/Bb)(α1•U + α2•ΔP•Δδ) + (2/Bb)Ue−1.2025a/w + 0.6233 for 0.3≤a/w≤0.53; ΔJ=(2/Bb)(α1•U + α2•ΔP•Δδ) + (2/Bb)Ue−0.02 sin[(π/0.23)(a/w−0.53)] for 0.53<a/w<0.95. This formula is applicable to the fatigue crack propagation range of 0.3≤a/w<0.95.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

High-Order Integral Equation Methods for Diffraction Problems Involving Screens and Apertures [PDF]
, 2012 This thesis presents a novel approach for the numerical solution of problems of diffraction by infinitely thin screens and apertures. The new methodology relies on combination of weighted versions of the classical operators associated with the Dirichlet ...

Plastic stress intensity factor behavior at small and large scale yielding
Fracture and Structural Integrity, 2020 In this paper the plastic stress intensity factor (SIF) is used to study the coupling effects of the loading biaxiality, the material properties and the cracked body configuration in both the small- and large-scale yielding ranges.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
