“…[34] Hence, eliminating these drawbacks and getting an effective conversion of energy hybrid/combined energy harvester is required. Several methods have been used to enhance the piezoelectric energy harvesters, such as loading criteria, [35,36] functionally graded designs, [37][38][39][40][41][42][43][44] and structural designs of the harvester. [45][46][47][48][49] There has been a rise in the application of auxetic structures for enhancing piezoelectric energy harvesters in recent years.…”

This study proposes a separate and combined (pyroelectric + piezoelectric) energy harvesting system using a bimetallic beam. Hybrid energy harvesting is achieved by waste thermal energy using thermal expansion mismatch of the bimetallic beam. In this regard, four types of design are proposed, along with various heating/cooling cycles. Auxetic layers in a bimetallic beam are used to enhance the power. The best‐performing design and heating/cooling cycle are considered for further power increment. Two models are simulated based on low (model C3) and high heat consumption (model C5). The load resistance, frequency, bimetallic beam and pyroelectric/piezoelectric layer thickness are varied and maximum power is obtained at 175 MΩ (C3), 75 MΩ (C5), 0.02 Hz (C3 and C5) and 0.4 mm (C3 and C5) as 20 μW (C3) and 40 μW(C5), respectively. The piezoelectric, pyroelectric and combined power variation is the effect of stress and temperature fluctuations on H‐PEH layer. Additionally, five well‐known higher pyroelectric/piezoelectric coefficient materials are studied and found that La‐NBT‐BT‐Ta gives the maximum power of 0.811 and 1.99 mW for combined (pyroelectric + piezoelectric) effect in low (C3) and high (C5) heat consumption model, respectively. The stress generated in both models is analyzed to look at practical feasibility.

“…Zhang et al [3] analyzed the wave propagation with different shear deformation beam theory in CNT cement composites. Mangalasseri et al [4] described the energy harvesting behavior of smart composites like magneto-electro-elastic material with CNT. The investigation shows that electromagnetic circuits influence the nonlinear frequency ratio and give a clear idea about boundary conditions, CNT volume fractions, and geometrical parameters such as aspect ratio and length-to-width ratio [4].…”

Represent Volume Element (RVE) is broadly used by investigators to control the properties of nano-cementitious materials. This paper focuses on analyzing a set of RVE data and proposes parametric equations for determining the compressive and flexural strength characteristics (σc and σf). Primarily, a parametric study is performed with RVE analysis. The essential design parameters are used to fit rational equations. The RVE data are also applied to train artificial neural networks of σc and σf. RVE, neural networks, and rational equations are correlated. Regression equations are validated with the experimental study. SEM, TEM, XRD, and FTIR results are carried out in the microscopic and mechanical analysis for carbon nanofiber cement composites, which can lift their strength, constancy, integrity, and density and reinforce the composite microstructure. Lastly, the Pareto-optimal design results are presented with a multi-objective optimization problem.

This work presents a detailed investigation of the effect of auxeticity synergised with the pyro-coupling behaviour of multiphase magneto-electro-elastic (M-MEE) composites using a finite element (FE) framework. The nonlinear deflection and bending problems of sandwich plates with auxetic core and M-MEE skins subjected to multi-physics load (electric, magnetic and thermal) are probed. The plate kinematics is governed by Reddy’s higher-order shear deformation theory (HSDT). The nonlinear relation between the strains and displacements is established through von-Karman’s nonlinear relations. The temperature profiles are considered linearly and nonlinearly varying across the thickness of the plate. Various parametric studies presented in this article highlight the influence of the auxetic cell inclination angle, rib-length ratio, rib thickness, the plate-to-core ratio etc., associated with the pyro-coupling on the nonlinear deflection and bending of sandwich plates. The results reveal that the plate deflection, bending behaviour and degree of pyro-coupling significantly depend on the auxetic unit cell dimensions and magnitude of electro-magnetic loads. The significant influence of temperature profiles on the pyro-coupling are witnessed at lower auxetic cell angle. The nonlinear deflections of the sandwich plate and hence the potentials developed tend to improve with the lower values of plate-to-core ratio and rib thickness. The prominent outcomes of this work related to integrated effects of auxeticity and pyro-coupling are not yet reported in the open literature and are deemed to be utilised as a future reference.
