Free Vibration of Curved Sandwich Beams with Laminated Composite Facings Using Finite Element Method
Abstract: The present work is focussed on the free vibration analyses of singly curved sandwich beams using three-dimensional finite element method in ABAQUS software. Three different layers are considered for soft core and stiff face sheets in ABAQUS solid modelling to accurately represent the effects of transverse shear deformation of sandwich structure. To validate the model, obtained natural frequencies from present model are first compared with the results available in the …

Enhancement of Mechanical Properties in Hemp Fiber-Reinforced Epoxy Composites Using Graphene Nanoplatelets
Abstract: This study investigates how incorporating graphene nanoplatelets (GNPs) influences the mechanical performance of hemp fiber–reinforced epoxy composites. Hemp fibers were chemically treated by alkali treatment to improve fiber–matrix adhesion owing to their high specific strength, stiffness, renewability, and environmental friendliness. Graphene nanoplatelets were dispersed in acetone by probe sonication and added to acetone epoxy matrix at a concentration of 0.5 wt% and 1.0 wt%, respectively. Composite laminates were prepared by …

Finite Element Modeling of Active Twist in Rotor Blades using IDE-PFC Actuators
Abstract: Blade Vortex Interaction in rotating helicopter blades contributes significantly to the instability and high vibration levels during its operations. It is therefore essential to evolve a mechanism to reduce unwanted vibration. Several methods/devices, like the smart trailing edge flap actuators, active blade twist, etc are suggested. Active blade twist concept deals with changing the angle of attack and thereby reducing vibration and noise. The piezoelectric actuators are the promising devices …

Numerical Investigation of Ply-by-Ply Failure and Strength Degradation in Composite Laminates Under Transverse Loading
Abstract: This paper represents the failure analysis of composite symmetric and antisymmetric laminate, when laminates were subjected to the transverse loading conditions. The load is uniformly distributed in a transverse direction. The analysis includes failure load and nature of failure by using theories of failure. The ply degradation material model is used to modify and update the properties of failed lamina and upgrades the properties of laminate. Laminate is modelled as …

Influence of Epoxy-Based Thermally Conductive Polymer Composites on the Thermo-Hydraulic Performance of Finned Helical Coil Heat Exchangers Across Flow Regimes
Abstract: The use of polymer composites in heat exchanger applications has gained increasing attention due to their advantages in weight reduction, corrosion resistance, and design flexibility. However, their relatively low thermal conductivity compared to conventional metallic materials remains a key limitation for efficient heat transfer. In this study, the thermo-hydraulic performance of a finned helical coil heat exchanger is investigated with particular focus on epoxy-based polymer composites reinforced with thermally conductive …
