In the previous chapter, in the models with pressure dependent stiffness, the shear modulus G was either constant or increased with the mean effective stress. These models used to describe the pre-yielding deviatoric behaviour of soils in standard triaxial compression tests reasonably well.

Small elastoplastic strains of dielectrics
Journal of Applied Mechanics and Technical Physics, 1975The theory of small elastoplastic strains of dielectrics in the presence of an electric field is developed in the work. An expression is obtained for the electric part of the stress tensor. Total free energy minimum theorems with constant temperature and simple proportional loading and unloading theorems are proved.

Mechanical anisotropy at small strains
1997The recognition that molecular orientation can produce important enhancement in the mechanical properties of polymers has long been appreciated, so it is perhaps surprising to find that detailed studies of the total mechanical anisotropy are comparatively rare.

The strain energy of cyclotetradecane is small
The Journal of Organic Chemistry, 1992Contrary to earlier reports, we show the strain energy of cyclotetradecane is both small and similar to that of other moderately sized cycloalkanes. Our finding is derived by use of semiempirical rules, MM3 molecular mechanical calculations, chemical intuition, and new measurements of head of sublimation (mean temperature=39 o C, 23.4 kcal mol -1 ...

Inhomogeneous strains in small particles
Surface Science Letters, 1985Abstract This paper considers the evidence for strains in small particles. Firstly, the dynamical electron diffraction theory for dark field imaging of small particles is briefly reviewed, considering primarily the effects of strain on wedge crystals and identifying the fingerprint of strain contrast effects under strong beam conditions.

Inelasticity of solids for small strains
Technical Physics Letters, 1999Residual (irreversible) deformations of solids were observed under very low stresses for strains e ≈10−6, which in the literature are traditionally classed in the elastic region. Inelastic deformations appeared in this range for all types of solids (mono-and polycrystals of plastic and brittle materials, amorphous solids) differing strongly in nature ...

Determining Elastic Soil Properties At Small Strains
12th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1999Geotechnical and geophysical techniques have been combined to determine the elastic parameters of a series of lacustrine clays at a location where series of highway underpasses are to be constructed. Piezocone penetrometer and triaxial tests on borehole core samples allowed variations of the soil structure and the shear modulus /J over a range of ...

A cell strain system for small homogeneous strain applications.
Biomedizinische Technik. Biomedical engineering, 1998A cell culture system has been developed that enables application of well characterized, homogeneously distributed cyclic strains to monolayer cell cultures. Optically clear silicone culture dishes atop Plexiglas base plates are deformed by four-point bending of flexible silicone culture wells driven in user specified strain cycle patterns using ...

Anisotropy of small strain stiffness in Ticino sand
Géotechnique, 1996Comprehensive tests performed in a large calibration chamber and consisting of the propagation of seismic body waves in dry Ticino silica sand are presented. By virtue of the fact that both shear and constrained compression waves have been propagated in vertical, horizontal and oblique directions, five independent constants of the cross-anisotropic ...

Nonlinear Behavior of Trabecular Bone at Small Strains
Journal of Biomechanical Engineering, 2000Study of the behavior of trabecular bone at strains below 0.40 percent is of clinical and biomechanical importance. The goal of this work was to characterize, with respect to anatomic site, loading mode, and apparent density, the subtle concave downward stress–strain nonlinearity that has been observed recently for trabecular bone at these strains ...
