Release of fish captured by recreational anglers is a common practice due to angler conservation ethics or compliance with fisheries regulations. As such, there is a need to understand the factors that influence mortality and sub-lethal impairments to ensure that catch-and-release angling is a sustainable practice. Longer angling times generally contribute to increased stress and mortality in f...

In this paper, a strain-intensity-factor-based method is proposed to calculate the fatigue crack growth under the fully reversed loading condition. A theoretical analysis is conducted in detail to demonstrate that the strain intensity factor is likely to be a better driving parameter correlated with the fatigue crack growth rate than the stress intensity factor (SIF), especially for some metall...

The study of debonding is of importance in providing a good understanding of the bonded interfaces of dissimilar materials. The problem of debonding of an arbitrarily shaped rigid inclusion in an infinite plate with a point dislocation of thin plate bending is investigated in this paper. Herein, the point dislocation is defined with respect to the difference of the plate deflection angle. An an...

Study 1 examined the association between intensity of postconcussive symptoms (PCS), impact of daily stress, and level of perceived stress over the past month in a group of healthy young adults. There was a significant relationship between intensity of PCS and impact of daily stress, as well as level of perceived stress over the past month, independent of the frequency of stressful events exper...

in this paper, the mixed-mode dynamic fracture analysis of a fgm plate is performed using mlpg method also the effect of changes in value and angle of material gradation on the dynamic stress intensity fctor(sif) of mode i, ii, and effective are investigated. to solve time dependent equations that discretized by mlpg method, the central difference method (cdm) and the newmark method are used. a...

It is shown that if the displacement field and stress intensity factor are known as functions of crack length for any symmetrical load system acting on a linear elastic body in plane strain, then the stress intensity factor for any other symmetrical load system whatsoever on the same body may be directly determined. The result is closely related to Bueckner's [1] "weight function". through whic...
