A new three-noded thermomechanical beam finite element is derived for the analysis of laminated beams. The mechanical part is based on a refined model. The representation of the transverse shear strain by cosine function allows avoiding shear correction factors. This kinematics accounts for the interlaminar continuity conditions at the interfaces between the layers, and the boundary conditions ...

The paper deals with the modelling and analysis of thick piezoelectric multilayer composite shell continua applied to accurate and optimal design of adaptive (smart) structural components and systems in industrial applications. The smart composite is made of n laminae, in which each lamina can be used as either actuator, sensor, self-sensing actuator, or passive structural component. A discrete...

An accurate coupled field piezoelectric beam finite element formulation is presented. The formulation is based on First-order Shear Deformation Theory (FSDT) with layerwise electric potential. An appropriate through-thickness electric potential distribution is derived using electrostatic equilibrium equations, unlike conventional FSDT based formulations which use assumed independent layerwise l...

Building upon recent works devoted to the development of a stress-based layerwise model for multilayered plates, we explore an alternative finite-element discretization conventional displacement-based method. We rely on mixed approach where both stresses and displacements are interpolated. Since conforming finite-elements ensuring traction continuity difficult construct, consider hybridization ...

Vibration suppression of smart beams using the piezoelectric patch structure is presented in the present work. The smart system consists of a beam as the host structure and piezoceramic patches as the actuation and sensing elements. An experimental set-up has been developed to obtain the active vibration suppression of smart beam. The set-up consists of a smart cantilever beam, the data acquisi...

Abstract In this paper, a beam theory for predicting limit point buckling and bifurcation of shallow arches composed two layers flexibly bonded is presented. The flexibility layer bond results in interlayer slip, which significantly affects the critical transverse loads. presented based on layerwise assumption Euler–Bernoulli linear behavior interlayer. After establishing equilibrium equations ...

Abstract This paper presents a beam theory for analyzing the static response of slightly curved three-layer beams with interlayer slip. Since are supposed to be immovably supported, membrane stresses develop even at moderately large deflections and becomes geometrically nonlinear. The is based on layerwise application Euler–Bernoulli linear elastic constitutive law interlaminar displacements. I...

Static shape actuation and dynamic control of nozzles can improve their performance, accuracy, reliability, etc. A new curved laminated piezothermoelastic hexahedral finite element is formulated based on the layerwise constant shear angle theory and it is used for modeling and analysis of piezothermoelastic conical shell structures subjected to control voltages for static shape actuation and dy...
