THERMAL EFFECTS ON NONLINEAR OSCILLATIONS OF HARD-MAGNETIC SOFT ACTUATORS S. Nandan, D. Sharma, A. Sharma World Congress in Computational Mechanics and Eccomas Congress, 2024 In recent years, there has been a growing interest in hard-magnetic soft materials (HMSMs) due to their capacity to retain high residual magnetization and undergo significant deformation when subjected to external magnetic loading.The performance of these materials in dynamic actuation modes is substantially affected by temperature.This article introduces a theoretical framework for modeling the dynamic behavior of hard-magnetic soft materials.The neo-Hookean material model is employed to account for the thermal properties of the HSM materials.The governing equation for dynamic motion is derived using Euler-Lagrange's principle for nonconservative systems, allowing the characterization of nonlinear oscillations under both constant and periodic magnetic fluxes.Dynamic stability, resonance properties, dynamic response, and periodicity are characterized using frequency response spectra, time history graphs, phase-plane diagrams, and Poincar maps.The investigation seeks to comprehend the transition from periodic to quasi-periodic oscillation behavior of actuators.These findings represent an initial step towards designing and developing remotely controlled actuators for various futuristic applications.
Viscoelastic Effects on the Nonlinear Oscillations of Hard- Magnetic Soft Actuators Shivendra Nandan, Divyansh Sharma, Atul Kumar Sharma Journal of Applied Mechanics Transactions ASME, 2023 The hard-magnetic soft materials (HMSMs) belong to the magnetoactive category of smart polymers that undergo large actuation strain under an externally applied magnetic field and can sustain a high residual magnetic flux density. Because of these remarkable characteristics, HMSMs are promising candidates for the remotely controlled actuators. The magnetic actuation behavior of the hard-magnetic soft actuators (HMSAs) is considerably affected by the viscoelastic material behavior of HMSMs. In this article, we aim at developing an analytical dynamic model of a typical planar model of HMSAs concerning the viscoelasticity of HMSMs. A Zener rheological model in conjunction with an incompressible neo-Hookean model of hyperelasticity and Rayleigh dissipation function is employed for defining the constitutive behavior of the viscoelastic HMSA. The governing equations of dynamic motion are deduced by implementing the nonconservative form of the Euler–Lagrange equation. The established dynamic model is utilized for providing preliminary insights pertaining to the effect of the viscoelasticity on the nonlinear oscillations of the actuator. The phase–plane portraits, Poincaré maps, and the time–history response are plotted to investigate the stability, resonant behavior, and periodicity of the actuator. The results and inferences reported here should provide the initial step toward the design and the development of modern actuators for diverse futuristic applications in the medical and engineering fields.
