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 ...

Strain fields at contacts between small particles
Journal of Colloid and Interface Science, 2003Stress fields between interacting small particles ( approximately 100 nm) have been investigated by transmission electron microscopy. The background for these TEM observations is discussed in terms of adhesion stress fields (due to surface forces), the action of an applied point force, possibly magnetic, and dislocations or misfit strains due to an ...

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.

Small Specimen Strain Measurement by Moiré Fringes
Journal of Dental Research, 1974The moiré fringe technique of strain analysis was applied to small beams of resin restorative materials. The feasibility of using this technique on small dental materials specimens was established.

Large Deformations with Small Strains
1972The solution of a problem of finite deformation may require knowledge of material properties not embodied in the linear stress-relaxation moduli. Then again, it may not. In some problems of finite deformation, no material element is distorted very much even though displacements and rotations are large.

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 ...

Small Strain Elastic Properties
1975Young’s modulus, and to some extent torsional rigidity, have been characteristic properties of polymeric materials quoted in both scientific and advertising literature for several decades, but, with few exceptions, only within the past 15 years has much attention been given to the less directly accessible elastic constants.

On the Kinematics of Deformations with Small Strain and Moderate Rotation
Mathematics and Mechanics of Solids, 2004In this paper we discuss kinematical issues of the theory of deformations resulting in a small strain accompanied by a moderate rotation. Here, by assuming appropriate measures of rotation and strain which are motivated by a scheme of approximation, we attempt to formulate a theory of small strains and moderate rotations which is consistent and ...
