Research on Structural behavior of Composite Materials on different Cantilever Structures using FSI

Abstract

The implementation of composite materials in industries like aerospace, automotive, civil, naval, etc., are emerging continuously because of its combined unique effects. The present article deals with a numerical simulation of the natural frequency effect on the different cantilever structure for various composite materials also estimates its structural response to aerodynamic forces using Fluid-Solid Interaction (FSI) in Ansys Workbench environment. This work is intended to analyze and learn the response of various real-time structural parameters like maximum deformation, maximum stress-induced location and modal parameters like modal frequency, mode shapes on different Cantilevered structures. Structures like wind turbines, airplane wings are critical in structural behavior, which are characteristically using the wind to produce power and lift respectively. The present article deals with an estimation of natural frequencies for the prediction of working lifespan and structural parameters variation throughout the cantilever structures to multi-purpose usage. The entire comparative part of this article is executed with an acceptable simulation of the displacement and principal stress for different composite materials such as Kevlar, Glass Fiber Reinforced Plastic (GFRP) and Carbon Fiber Reinforced Plastic (CFRP) by using FSI. Composites Beams are modeled in CATIA and discretized in the Ansys ACP 16.2 tool and Modal analysis of various crosssectional beams are reported, compared and discussed.

Design and Computational Analyses of Nature Inspired Unmanned Amphibious Vehicle for Deep Sea Mining

“…Density, young's modulus, bulk modulus, and Poisson's ratios, especially, were major focused initial conditions for computational structural analyses. Hence, the works [32][33][34][35] executed were supported hugely to attain the aforesaid properties. Finally, earlier applications completed by the UAmVs were collected, wherein the involvement of major and minor components for their mission executions were completely recorded.…”

“…Whereas the coefficient of lift predominantly relies on two factors when the UAmV undergoes the mission under the water: the weight of the UAmV and the buoyancy force. From the literature survey [32][33][34][35], the suitable lightweight materials shortlisted are Carbon Fibre Reinforced Polymer (CFRP), Glass Fibre Reinforced Polymer (GFRP), aluminium alloy, magnesium alloy, and grey cast iron. All of these materials have a higher density than water, thus the occurrence of buoyancy force is mandatory when the UAmV has initiated submersible manoeuvring.…”

Multi-disciplinary Optimizations on Flexural Behavioural Effects on Various Advanced Aerospace Materials: A validated investigation

“…While in the case of fundamental property investigation, the ASTM provides the uniform design parameters to support the construction of numerical model based on its nature of the test and its material's properties. The nature of this work is aimed to analyze the flexural property of various composite materials in multi-disciplinary perspectives [12][13][14][15]. Therefore, this work is finalized to use the design parameters from ASTM D7264 where the dimensions are length span as 100 m, width as 20 mm, and thickness as 7 mm.…”

Multi-Disciplinary Computational Investigations on Asymmetrical Failure Factors of Disc Brakes for Various CFRP Materials: A Validated Approach

“…Later machining creates intricate forms. Adding enough filler to the matrix improves primary composite qualities [5][6][7][8][9][10].…”

“…Symmetrical factors such as tensile failure and bending failure are directly connected to the applied external load and the produced internal resistive force [7]. In the case of non-linear (asymmetrical) failure, causes such as shear, impact loads are uncontrollable, generating an uncontrolled resistive force on the item's interior structure [8]. A change in atomic structure may cause catastrophic failure.…”
