Design and Strength Safety Analysis of Pressure Relief Device for Perforating Gun
Perforation detonation produces high-temperature and high-pressure gas. If the pressure exceeds the internal pressure strength of the gun body, the perforating gun would break, leading to accidents such as gun expansion and jamming.

A study of fatigue crack closure using electric potential and compliance techniques [PDF]
Compared are closure data produced on the same specimen by the crack tip compliance gage and electric potential techniques. Experiments on 7075-T651 aluminum center cracked panels produced equivalent results on closure using the two techniques.

Finite element stress analysis of polymers at high strains [PDF]
A numerical analysis is presented for the problem of a flat rectangular rubber membrane with a circular rigid inclusion undergoing high strains due to the action of an axial load.

We present numerical investigations based on the Luttinger-Kohn four-band $k \cdot p$ theory and, accordingly, establish a quantitatively valid model of the excitonic fine structures of droplet epitaxial GaAs/AlGaAs quantum dots under uni-axial stress ...

Atomic-level Stress Calculation and Continuum-Molecular System Equivalence
An atomistic level stress tensor is defined with physical clarity, based on the SPH method. This stress tensor rigorously satisfies the conservation of linear momentum, and is appropriate for both homogeneous and inhomogeneous deformations. The formulation is easier to implement than other stress tensors that have been widely used in atomistic analysis,

Body force equivalents for stress-drop seismic sources [PDF]
abstract The equivalent body forces for a stress-drop seismic source are found. When the isotropic stress drop and one of the three principal stress drops are zero, then the equivalent body forces are the same double couple without moment which would result from a shear dislocation. In general however, all six stress-drop components must

Models of stress fluctuations in granular media
We investigate in detail two models describing how stresses propagate and fluctuate in granular media. The first one is a scalar model where only the vertical component of the stress tensor is considered.
