STRESS DISTRIBUTIONS AND FAULTING

Geological Society of America Bulletin, 1951
Tectonic deformations result from a condition of internal stress caused, in turn, by primary and secondary forces. In the geological literature, a great deal of discussion is based on a direct connection between forces and deformation, completely by-passing the concept of stress.

stress Distribution at an Overfall

Transactions of the ASAE, 1989
ABSTRACT THE formation and movement of a headcut in an earth emergency spillway often constitutes the major source of damage to the structure. The mechanics of headcut formation and growth are, however, largely unknown. The following paper describes current research in measuring the hydraulic stresses at the boundary of a turbulent overfall.

Stress distribution in the muscles of the diaphragm

2000
Summary: The diaphragm is treated as a membrane subject to a uniform pressure, and the muscle action is modeled as a uniaxial active stress in the direction of muscle bundles. We look for the generalized stress distribution in the membrane. The shape of the active diaphragm is approximated by a surface know as a cyclide.

Analysis of stress distribution by endodontic posts

Oral Surgery, Oral Medicine, Oral Pathology, 1972
Abstract Three commonly used endodontic post designs, their lengths, their methods of insertion, and their abilities to transmit occlusal forces to supporting structures were compared. According to this photoelastic stress analysis, post design affects stress distribution.

Distributions of load stresses and residual stresses at notches

KSME Journal, 1992
The fatigue strengh reduction factor K, can be mitigated or eliminated by suitable surface treatments. Analysis of these affects requires the knowledge of the distributions of load stresses and of residual stresses below the surface of notches. This paper describes a simple, approximate formula to determine load stress distributions and residual stress

Stress distribution in helium-ion implantations☆

Journal of Nuclear Materials, 1976
Abstract The stress introduced into a material in a monoenergetic helium-ion implantation is calculated for a ion beam with a gaussian intensity distribution. An effective beam spot of the order of several millimeters was chosen as typical of blistering experiments. The sample is assumed to be semi-infinite and isotropic.

Stress Intensity Factors for a Linear Stress Distribution

2003
The stress intensity factor for an edge crack of length a in a semi-infinite plate subjected to a pair of equal and opposite concentrated forces at a distance b from the plate edge (Figure 1) is given by [1] $$ K'_I = \frac{2} {{\sqrt \pi }}\frac{{1 + F\left( {{b \mathord{\left/ {\vphantom {b a}} \right.
