Effect of heel height on in-shoe localized triaxial stresses

Journal of Biomechanics, 2011
Abnormal and excessive plantar pressure and shear are potential risk factors for high-heeled related foot problems, such as forefoot pain, hallux valgus deformity and calluses. Plantar shear stresses could be of particular importance with an inclined supporting surface of high-heeled shoe. This study aimed to investigate the contact pressures and shear

Growth and Closure of Voids in Metals at Negative Stress Triaxialities

Key Engineering Materials, 2013
Damage of metals subjected to large plastic deformations typical for forming processes is mainly governed by void nucleation, growth and coalescence. An opposite process may occur in deformation processes with negative stress triaxialities: the closure of strain-induced defects under large hydrostatic pressure.

Stress-Controlled Apparatus for Triaxial Testing

Journal of the Soil Mechanics and Foundations Division, 1967
A testing machine in which the rate of true stress can be controlled manually or automatically is described. A pneumatic analog computer continuously calculates the cross section of the test specimen and provides the loading unit with a pressure such that the force applied produces a given axial stress.

The triaxial vane apparatus with stress control.

2009
The scope of this research has been two fold. The first stage was to develop a Tri Vane Apparatus. The Tri Vane Apparatus uses a miniature vane incorporated into a triaxial cell in order to study the use of the vane in different soils as well as allowing the effects of different vane parameters, such as rotation rate and vane geometry, to be studied in

Stress around pressurized spherical cavities in triaxial stress fields

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1974
Abstract The stress at a given point around a pressurized spherical cavity in an applied triaxial stress field can be calculated using the equations presented in this article. The spherical cavity is assumed to be buried at a depth of greater than 6 cavity radii and the applied triaxial stress field is assumed to be constant.
