Abstract Magnetostrictive materials are potential candidates for many applications such as sensors, actuators, transducers, and other magnetoelectric applications. Cobalt Ferrite (CoFe2O4) has proven to be favourable in comparison to commonly used magnetostrictive materials due to its high magnetostriction coefficient and it’s preparation being cost effective. This work deals with the preparation of CoFe2O4 (CFO) using four different wet chemical synthesis techniques in the form of autocombustio...

Abstract Amorphous thin film metallic glasses (TFMGs) have given rise to a widespread research interest due to their technological promise for practical applications and scientific importance in the biomedical field. As a result of their disordered atomic structure (leading to amorphicity), these TFMGs symbolize a new class of structural and functional materials with extraordinary properties, including exciting strength along with superior mechanical properties and biological properties. TFMG to...

Abstract null null Corrugated structures are made up of panels with periodic profiles. These are used as a compliant mechanism and as core in sandwich plates for their direction dependent stiffness. Modeling and large deflection analysis of corrugated structure play an essential role in their design and application. This work proposes an iterative scheme for the large deflection analysis of double corrugated cantilever structures subjected to end point loads and uniformly varying load using a ch...

Abstract The aim of our study is to investigate the effect of boron with different ratios in Ti-Cu-Pd-Zr metallic glass (MG) matrix (Ti-Cu-Pd-Zr:B) fabricated by Pulsed Laser Deposition (PLD) for biomedical implants. The Ti based Thin Film Metallic Glasses (TFMGs) in combination with boron (in different atomic %) was assessed in attaining the combined properties, like outstanding corrosion resistant properties and good biocompatibility in this work. The disordered structure and amorphous nature ...

The traditional [0/90]T laminate has two stable equilibrium shapes, and it is possible to go from one shape to the other by means of an external force. In the past, researchers have attempted to obtain the snap-through between the two equilibrium states using smart actuators like shape memory alloy (SMA) wires and macro-fiber composite (MFC) patches. The integration of these actuators adds several complications. Moreover these smart actuators are generally attached to the surface of the laminate...

Abstract This manuscript investigates the snap-through characteristics of a special class of hybrid bistable symmetric laminate (HBSL) subjected to different loading constraints and imperfections. Understanding the behavior under various loading conditions and constraints is necessary to deploy these bistable laminates in structural applications. Towards that, detailed experimental and numerical studies are done to capture the load–displacement characteristics of: (a) an HBSL clamped at differen...

Abstract Lead-free Na0.4K0.1Bi0.5TiO3 (NKBT) and NiFe2O4 (NFO) ceramics are synthesized by solid-state reaction, and the laminated NKBT/NFO composites have been prepared by gluing the sintered discs with silver-epoxy. The measured parameters, dielectric constant (e′) ∼1450 at 1 kHz, remanent polarization (Pr)∼39 µC/cm2, coercive electric field (Ec)∼27 kV/cm and maximum strain (Smax)∼0.3 % of NKBT along with saturation magnetization (Ms)∼49 emu/g, coercive magnetic field (Hc)∼27 Oe and magnetostr...

This manuscript proposes an iterative scheme for geometrically large deflection analysis of corrugated structures using the nonlinear shooting method. The corrugated structure is modeled by discretizing it in several corrugated units. The solution of each unit is obtained assuming it to be consistering of several beam elements. Finally, the deflection of a corrugated structure is calculated assembling the deflection of each of the corrugated units. The formulation has been extended to various bo...
