Abstract In the present work, two-phase integral theory of elasticity developed in Barretta et al. (Phys E 97:13–30, 2018) for nano-beams is generalized to model two-dimensional nano-continua. Notably, a well-posed mixture local/stress-driven nonlocal proposed accurately predict size effects Kirchhoff axisymmetric nanoplates. The key idea express elastic radial curvature as convex combination l...

This paper deals with the dynamic characterisation of plate structures elliptical orthotropic stiffness properties, using an equivalent thin theory a wave fitting approach. The method consists in projecting experimentally determined transverse displacement field on analytical Green’s function based Hankel’s functions. error between projected and measured fields is then minimized, varying charac...

A range of elliptical undulators (EU) has recently been constructed at ELETTRA, whose main parameters are listed in Table 1 below. They are all based on the APPLE-II scheme [1], but two different terminations have been used due to specific installation requirements. Also, one of them (EU12.5) features a quasi-periodic field to suit special beamline needs. The minimum magnetic gap corresponds to...

In this study, efficient methods for optimal sensor placement (OSP) based on a new geometrical viewpoint for damage detection in structures is presented. The purpose is to minimize the effects of noise on the damage detection process. In the geometrical viewpoint, a sensor location is equivalent to projecting the elliptical noise on to a face of response space which is corresponding to the sens...

We present a phase plate loading system developed for a commercial transmission electron microscope (TEM). Our system can be installed without modifying the optical design of the TEM. This system is equipped with a loading monitoring set that allows users to easily and safely locate the phase plate between the pole pieces, and also comes with an airlock that permits quick loading of a phase pla...

An ideal bone plate for internal fixation of bone fractures should have good biomechanical properties and biocompatibility. In this study, we prepared a new nondegradable bone plate composed of a ternary nano-hydroxyapatite/polyamide 66/glass fiber (n-HA/PA66/GF) composite. A breakage area on the n-HA/PA66/GF plate surface was characterized by scanning electron microscopy. Its mechanical proper...

We consider deflections of a thin rectangular elastic plate that is submerged within a Newtonian fluid. The plate is clamped along one edge and supported horizontally over a plane horizontal wall. We consider both external driving, where the clamped edge is vibrated vertically at high frequencies, and thermal driving, where the plate fluctuates under Brownian motion. In both cases, the amplitud...
