Anisotropic elasticity of experimental colloidal Wigner crystals.
Colloidal particles interacting via a long-range repulsion can, in contrast to hard-sphere systems, exhibit crystalline ordering at low volume fraction. Here we experimentally investigate the structure and properties of such "colloidal Wigner crystals." We find a body-centered-cubic crystalline phase at volume fractions of ϕ≳15%, which exhibits large fluctuations of individual particles from th...
متن کاملExperimental investigation of the elasticity of the human diaphragm
BACKGROUND Traumatic diaphragmatic ruptures affect mainly the left side. In an experimental study in human corpses we examined the stretch behaviour of the left and right diaphragmatic halves. METHODS In a total of 8 male and 8 female corpses each diaphragmatic half was divided into 4 different segments. Each segments stretch behaviour was investigated. In steps of 2 N the stretch was increas...
متن کاملExperimental Cosserat elasticity in open cell polymer foam
Reticulated open cell polymer foams exhibit substantial size e↵ects in torsion and bending: slender specimens are more rigid than anticipated via classical elasticity. Such size e↵ects are predicted by Cosserat (micropolar) elasticity, which allows points to rotate as well as translate and incorporates distributed moments (couple stresses). The Cosserat characteristic length is larger than the ...
متن کاملExperimental determination of the elasticity of iron at high pressure
[1] We present a multitechnique approach to experimentally determine the elastic anisotropy of polycrystalline hcp Fe at high pressure. Directional phonon measurements from inelastic X-ray scattering on a sample with lattice preferred orientation at 52 GPa in a diamond anvil cell were coupled with X-ray diffraction data to determine the elastic tensor. Comparison of the results from this new me...
متن کاملThe Elasticity of Elasticity
In this talk I assert that the usual interpretation of what one means by “elasticity” is much too insular and illustrate my thesis by introducing implicit constitutive theories that can describe the nondissipative response of solids. I show that response which was hitherto untenable within the context of Cauchy or Green Elasticity are not only possible, they can explain phenomena that have thus...
