Geometrically nonlinear finite element simulation of smart laminated shells using a modified first-order shear deformation theory

Abstract: This article investigates geometrically nonlinear and linear analysis of multilayered shells with integrated piezoelectric materials. An efficient nonlinear shell element is developed to solve piezoelastic response of laminated structure with embedded piezoelectric actuators and sensors. A modified first-order shear deformation theory is introduced in the present method to remove the shear correction factor and improve the accuracy of transverse shear stresses. The electric potential is assumed to be a linear … Show more

“…The ANS method is adopted in the current discrete model to avoid locking problems, which may improve the efficiency of the present model in the prediction of dynamic behavior. Therefore, shear strain is expressed as (Mallek et al, 2019b)…”

“…Let us consider bold-italicXp and bold-italicxp to be the position vectors of one point p of the mid-surface in the reference configuration C 0 and the current configuration C t , respectively. The position vector of one point q of the shell structure located at distance z from the mid-surface can be defined as (Mellouli et al, 2019a, 2019b, 2019c)where h is the thickness; bold-italicD is the initial shell director, which is perpendicular to the undeformed mid-surface; and bold-italicd1 and bold-italicd2 represent the double director shell vectors in the deformed configuration (see Figure 2).

“…The approach was recently extended by Carrera et al [12,13] in order to locally increase the accuracy by means of node-dependent kinematics. Furthermore, both geometrically [14,15,16] and materially [17] nonlinear problems in the behavior of piezoelectric thin-walled structures were also considered in the work of many researchers.…”

“…Recently, the use of composite materials in structures due to their applications and properties has been widely developed. Some new research studies were numerically and experimentally studied the nonlinear behavior of composite plate and shells (Pradyumna and Nanda, 2013;Sossou, 2012;Rezaiee-Pajand et al, 2018b;Tornabene and Reddy, 2013;Mallek et al, 2019a;Mallek et al, 2019b). After proposing FGMs, many articles were presented to investigate different static and dynamic behaviors of structures composed of this type of materials (Rezaiee-Pajand and Rezaiee-Pajand et al, 2018d;Tornabene and Viola, 2013;Tornabene, 2009;Viola and Tornabene, 2009;Mellouli et al, 2019).…”
