Finite Elastic Strain of Cubic Crystals

, 1947
Murnaghan's theory of finite strain is developed for a medium of cubic symmetry subjected to finite hydrostatic compression, plus an arbitrary homogeneous infinitesimal strain. The free energy is developed for cubic symmetry to include terms of the third

High-speed electrically actuated elastomers with strain greater than 100%

Science, 2000
Electrical actuators were made from films of dielectric elastomers (such as silicones) coated on both sides with compliant electrode material. When voltage was applied, the resulting electrostatic forces compressed the film in thickness and expanded it ...

Ultrahigh strain and piezoelectric behavior in relaxor based ferroelectric single crystals

, 1997
The piezoelectric properties of relaxor based ferroelectric single crystals, such as Pb(Zn1/3Nb2/3)O3–PbTiO3 and Pb(Mg1/3Nb2/3)O3–PbTiO3 were investigated for electromechanical actuators.

Strain and strain relaxation in semiconductors

Journal of Materials Science: Materials in Electronics, 1997
Single-crystal semiconductor layers can be grown with large coherency strains. This review covers their standard elasticity theory and methods of measuring the strain. High-quality strained layers are thermodynamically stable up to a critical thickness, and both theoretical and experimental determinations of critical thickness are considered.

Aspects of strain measures and strain rates

Acta Mechanica, 1986
In finite homogeneous deformation processes, the principal triad generally rotates with respect to a material element during the deformation. The material derivative of the logarithmic strain is no longer simply related to the rate of deformation tensor, and this is exemplified herein.

Development of four self-report measures of job stressors and strain: Interpersonal Conflict at Work Scale, Organizational Constraints Scale, Quantitative Workload Inventory, and Physical Symptoms Inventory.

Journal of Occupational Health Psychology, 1998
Despite the widespread use of self-report measures of both job-related stressors and strains, relatively few carefully developed scales for which validity data exist are available. In this article, we discuss 3 job stressor scales (Interpersonal Conflict

Plane-Strain Bending With Isotropic Strain Hardening at Large Strains

Journal of Applied Mechanics, 2010
Finite deformation elastic-plastic analysis of plane-strain pure bending of a strain hardening sheet is presented. The general closed-form solution is proposed for an arbitrary isotropic hardening law assuming that the material is incompressible. Explicit relations are given for most popular conventional laws.

Adductor Strain (Groin Strain)

2017
Adductor tendonitis is pain at the medial groin secondary to injury to the adductor muscle group or its insertional site. It is believed to be caused by inflammation and collagen dysfunction due to microtrauma during activities that require bursts of speed or quick directional changes.
