Dynamic analysis and damping of composite structures embedded with viscoelastic layers

Mixed integer multi-objective optimization of composite structures with frequency-dependent interleaved viscoelastic damping layers

“…Rikards et al [11] studied the damping features of laminated visco-elastic sandwich beams using finite elements. Rao et al [12] proposed a finite element based modal strain energy method to analyze laminated composite beams with embedded multiple damping layers. Three dimensional solid elements were used to model the viscoelastic material (VEM) and shell elements to discretize the elastic layers in their study.…”

Asymptotic analysis on flexural dynamic characteristics for a sandwich plate with periodically perforated viscoelastic damping material core

“…Subsequently, there are plenty of researchers who investigated VDM beam plate and shell structures. For example, Mead and Markus [6,7], Yan and Dowell [8], Rao et al [9], Kristensen et al [10], Kumara and Singh [11], and Sher and Moreira [12] are typical researchers in this area. Traditionally, VDM has four methods of application in industry, which is free layer damping, constrained layer damping [11,13] and partially constrained layer damping [14], and active constrained layer damping [15,16].…”

A damped sandwich beam model based on symmetric–deviatoric couple stress theory

“…Leibowitz and Lifshitz (1990) carried out experimental verification of parameters for a 3-layered sandwich beam with viscoelastic core. Rao, Echempati, and Nadella (1997) presented an analysis of the dynamic properties of multiple damping layer, laminated composite beams with anisotropic stiffness layers by means of the finite-element-based strain energy method. Baber, Maddox, and Orozco (1998) proposed a finite element model for harmonically excited viscoelastic sandwich beams.…”
