Static and Dynamic Analysis of Smart Functionally Graded Beams

This work presents the Static and Dynamic Analysis of Smart Functionally Graded Beams. Analysis has been performed by the finite element (FE) method for separate boundary conditions and loading. The effectiveness of piezoelectric material integrated onto the functionally graded (FG) beams is evaluated. The functionally graded beam is understood to be graded all along its thickness following power law distribution technique. Simulation models are developed in the ANSYS Workbench environment. Discretisation of the model is performed using an appropriate 20 node quadratic element (SOLID 226). The constitutive relation of piezoelectric material depends on coupling among elasticity and electric effect. Various static and dynamic analyses are carried out using different power law constants and boundary conditions. The observations are validated with the values reported in papers published by earlier researchers. Effects of boundary conditions as well as material properties are studied. The results are also compared among those for functionally graded beams and smart functionally graded beams for both static and dynamic analyses. (C) 2018 Elsevier Ltd. All rights reserved.
