Key elastic properties of full-sized wood composite panels (WCPs) must be accurately determined not only for safety, but also serviceability demands. In this study, the modal parameters of full-sized WCPs supported on four nodes were analyzed for determining the modulus of elasticity (E) in both major and minor axes, as well as the in-plane shear modulus of panels by using a vibration testing m...

We study the elastic properties of a two-dimensional fluctuating surface whose area density is allowed to deviate from its optimal (Schulman) value. The behavior of such a surface is determined by an interplay between the area-dependent elastic energy, the curvature elasticity, and the entropy. We identify three different elastic regimes depending on the ratio Ap/As between the projected (frame...

The theoretical foundation of a variant on effective medium theories for elastic constants of composites is presented and discussed. The connection between this approach and the methods of Zeller and Dederichs, Korringa, and Gubernatis and Krumhansl is elucidated. A review of the known relationships between the various effective medium theories and rigorous bounding methods for elastic constant...

The deformation and mechanical behavior of individual zeolitic-imidazolate framework (ZIF-8) micro- and sub-microcrystals were observed under compression. Young's modulus and volume changes as a function of applied pressure were determined on individual single crystals, offering insights in the relationship among structure, morphology, and mechanical properties. Dramatic volume decreases and am...

Based on the work of Pinkall, characterizations of spherical curves are given whose corresponding Hopf cylinders are isothermic surfaces in the threedimensional sphere. Comparing these characterizations with results of Langer and Singer about elastic spherical curves we determine all isothermic Willmore Hopf tori.

In this paper we discuss work on the use of diffusion tensor MRIs for inter-subject brain matching. A multiresolution elastic matching algorithm, [2-4], for spatial normalisation of 3D image data, has been adapted for use with diffusion tensor data. The hope is that by exploitation of the added information contained in the diffusion tensor image, improved anatomical matches can be found, partic...

A method suitable for computing fluid flow in the presence of moving boundaries is presented. In particular, the interaction of fluid with elastic walls is considered. The flow solver was developed based on artificial compressibility concept. The discrretization is done on unstructured tetrahedral meshes. A model of fluid interaction with elastic boundaries including boundary and mesh deformati...

A wave traveling upward through a particle bed is observed to steepen and form a shock as the surface is approached. This steepening is due to the increase in the local speed of sound that is induced by the local pressure increase in the upward moving phase of the wave behind the wave front. The pressure increase leads to an increase in the local coordination number which in turn increases the ...

Lorenzo Gotte (1926-1991) was an outstanding histologist at the School of Medicine of Padua. This year marks the 25th anniversary of his passing away - commemorated during the recent congress of the Italian Society for the Connective Tissue (SISC), held in Padua (September 30 - October 1, 2016). This brief note recalls this outstanding figure: indeed, forthose who knew him, Lorenzo Gotte was an...
