In precast concrete segmental tunnels, radial and circumferential joints are often the most highly stressed ... This paper assesses the accuracy of published equations for bursting force and peak ...

In Eq. 6, the relationship between principal stresses and geometric parameters of the borehole (elliptical semi-major axis A and semi-minor axis B and initial radius r) forms the theoretical basis of ...

The circumferential stress (also known as hoop stress) is simply tensile stress acting tangential to the vessel's circumference. And the effect of this may split the pipe into two halves. It can be ...

During the theoretical derivation, the plastic zone is divided into some annuli, with the thickness determined by a constant radial stress increment. Then, the analytical solution of each annulus is ...

In this paper, the copper-paper layered ring winding model, which can be analyzed as a 2D stress distribution problem, has been constructed. The governing equation for this model in polar coordinate ...

Magnetic resonance imaging (MRI) can measure cardiac response to exercise stress for evaluating and managing heart ... With golden-angle radial acquisition, parallel imaging and compressed sensing can ...
