Assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. Using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. In this paper, deformations, crushing length, peak load, mean force and energy absorption cap...

Abstract The indentation test is a promising technique for the viscoelastic characterisation of asphalt concrete (AC). Indentation measurements are primarily influenced by material properties in direct vicinity indenter-specimen contact point. Accordingly, it may become useful alternative thin layers as well quasi-non-destructive AC field. In this study, spherical used to measure linear mixture...

A non-quasi-static compact model well suited for the simulation of electrical behavior printed organic thin-film transistors (OTFTs) is proposed and validated. The based on discretization current continuity equation by using a spline collocation approach while transport in semiconductor described variable range hopping theory. accounts presence parasitic regions that are often found layouts OTF...

This paper describes a method to model thin-film fully-depleted (FD) silicon-on-insulator (SOI) MOSFETs at frequencies where the quasi-static model is no longer valid. The method consists in considering a cascade of several elementary MOSFET transistors or sections and applying the quasi-static analysis to each section. Important second-order effects such as mobility degradation and velocity sa...
