In order to understand the phenomenon of reversible plasticity exhibited by shape memory alloys and other smart materials, we study an elementary prototypical model. Building on an original idea of Müller and Villaggio [17], we consider an inhomogeneous ensemble of bi-stable elements connected in series and loaded in a soft device. To interpret the fine(More)
We study a simple mechanical model whose aim is to reproduce basic physical mechanisms behind reversible surface attachment-detachment under quasi-static loading. At the micro level the adhesive layer is modeled as an elastic chain of particles interacting with a rigid foundation through breakable springs. This model can be viewed as prototypical for the(More)
This work presents and describes a 20-year long database of GPS data collected by geodetic surveys over the seismically and volcanically active eastern Sicily, for a total of more than 6300 measurements. Raw data were initially collected from the various archives at the Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Catania-Osservatorio Etneo(More)
