TL;DR: In this paper, the authors presented a comprehensive finite element model for the numerical simulation of Hydrogen Induced Cracking (HIC) in steel pipelines exposed to sulphurous compounds, such as hydrogen sulphide (H2S), in order to mimic the pressure build-up mechanism related to the recombination of atomic hydrogen into hydrogen gas within the crack cavity.

TL;DR: Dimensional analysis of the governing equations shows that transient pressure application in a high-pressure food process does not enhance structural inactivation (mechanical damage), unless pressure oscillation frequencies of 700 MHz are applied.

TL;DR: The obtained hydrostatic stress dependence on the spacer layer thickness shows a nearly linear inverse dependence, unlike the commonly used inverse cubic dependence derived in the framework of an isolated embedded force dipole source model.
Abstract: Stress distribution in laterally ordered arrays of coherent Ge islands on Si(001) buried in Si cap layers is examined using atomistic simulations. The obtained hydrostatic stress dependence on the spacer layer thickness shows a nearly linear inverse dependence, unlike the commonly used inverse cubic dependence derived in the framework of an isolated embedded force dipole source model. Additionally, the hydrostatic stress on the spacer surface is found to scale more closely with the area of the island rather than its volume as implicit in the use of the force dipole model.

TL;DR: The accelerated osteogenesis in regions of high shear and the increased synthesis of proteoglycans in areas of high compressive hydrostatic stress are consistent with the theory which predicts the regulation of cartilage maintenance and endochrondral ossification by intermittent tissue stresses.

TL;DR: In this article, a 3D modified boundary layer analysis is performed using the finite element method to study the crack-front constraint for an elastic-plastic thin plate, and the results show that the in-plane-stress fields at the crack front for various K I − T loads possess the plane-strain nature throughout the thickness except for the region near the free surface, and can be characterized by the J-A 2 three-term solution under the small scale yielding condition.
