Mathematical Model and Analysis of a Laminated Curved Beam with Shear

Abstract

We present a mathematical framework to provide general well-posedness and approximation results for a laminated curved beam. The layered beam consists of an elastic core layer, symmentric viscoelastic damping layers, symmetric constraining layers and bonded piezoceramic patch pairs on the outer surfaces. The model includes unbounded inputs from the piezoceramic patches, hysteresis and shear in the viscoelastic layers. The viscoelastic layers are held in place by sandwiching them between the elastic core and elastic constraining layers. Families of linear and cubic splines are used to illustrate the approximation idea.
