Deformation Analysis of Perforated Sheets using Computational Homogenization
نویسنده
چکیده
Introduction Perforated sheets are used in a number of industrial applications e.g. the shadow masks in colour monitor and television tubes. Their design requires the characterization of the deformation behaviour of a perforated sheet containing a large number of tiny holes. In practice, the holes are varying through the sheet thickness, however, in modelling this inhomogeneity is mostly ignored and the holes are assumed to be cylindirical. These models fail to describe the real deformation behaviour.

Large Amplitude Vibration Analysis of Graphene Sheets as Resonant Mass Sensors Using Mixed Pseudo-Spectral and Integral Quadrature Methods
The present paper investigates the potential application of graphene sheets with attached nanoparticles as resonant sensors by introducing a nonlocal shear deformation plate model. To take into account an elastic connection between the nanoplate and the attached nanoparticle, the nanoparticle is considered as a mass-spring system. Then, a combination of pseudo-spectral and integral quadrature m...

In this paper, the effect of different boundary conditions on the free vibration analysis response of a sandwich plate is presented using the higher order shear deformation theory. The face sheets are orthotropic laminated composites that follow the first order shear deformation theory (FSDT) based on the Rissners-Mindlin (RM) kinematics field. The motion equations are derived considering the c...
