Combined Damping Effect of the Composite Material and Magnetorheological Fluid on Static and Dynamic Behavior of the Sandwich Beam

Enhancing Structural Integrity of Composite Sandwich Beams Using Viscoelastic Bonding with Tapered Epoxy Reinforcement

“…Nagiredla et al 27) proposed grading viscoelastic materials axially in sandwich beams to improve dynamic response for structural applications. A validated finite element code was generated using Lagrange's method for equations of motion (EOM) and finite element (FE) formulations based on classical beam theory.…”

“…From the above studies, it is clear that Zhou et al 15) it does not consider the combined effects of temperature and moisture, which have a different impact on bending properties and failure processes, in Mansourinik and Taheri-Behrooz 16) specific layup sequences and beam lengths restrict the results' applicability, in Zhang et al 17) advanced analytical models are required to accurately predict dynamic behavior, in Wei et al 18) the core indentation that was not observed throughout the trials is not depicted on the three-dimensional failure mechanism map, in Selvaraj et al 19) the results were inconsistent because of limitations in the production of sandwich beams, in Zhang et al 20) the parametric research Enhancing Structural Integrity of Composite Sandwich Beams Using Viscoelastic Bonding with Tapered Epoxy Reinforcement 129 thoroughly covers the effects of these variables on the failure modes of the beam and the resistance to beam shear, in Madenci et al 21) the inherent frequencies of sandwich plates with soft cores cannot be predicted with accuracy by higherorder theories, in Kallannavar and Kattimani 22) modelling their behavior correctly can be challenging due to mistakes in the prediction of natural frequencies and mode shapes, in Kashani and Hashemi 23) meshing errors lead to inaccurate solutions, in Wang et al 24) the volume fractions of graphene vary from one layer to the next, leading to different graphene distribution patterns throughout the thickness. In Shah et al 25) the catastrophic failure in completely 3D-printed SCS with GFRP factsheets due to higher bending stress, Madenci et al 26) applicability to other laminate types and failure modes is limited, and in Nagiredla et al 27) fails to describe the complicated behavior of sandwich beams, particularly in nonlinear or high-frequency dynamic scenarios. An innovative technique needs to be developed to prevent interlaminar delamination and increase the rigidity of composite sandwich beams.…”
