“…Thermo-magneto-electro-elastic materials have been popularly used in microelectromechanical systems (MEMs) and nanoelectromechanical systems (NEMs) applications in recent years [1][2][3][4][5]. Since the mechanical properties of these materials may be affected by both magnetic and electric potential [6,7], they have great usage advantages in many applications such as micro and nano scale soft robotic actuator, wearable technology, nano drug transfer [8][9][10][11][12][13][14][15].…”

This study investigates the behavior of free vibrations in a variety of porous functionally graded nanobeams composed of ferroelectric barium-titanate (BaTiO3) and magnetostrictive cobalt-ferrite (CoFe2O4). There are four different models of porous nanobeams: the uniform porosity model (UPM), the symmetric porosity model (SPM), the porosity concentrated in the bottom region model (BPM), and the porosity concentrated in the top region model (TPM). The nanobeam constitutive equation calculates strains based on various factors, including classical mechanical stress, thermal expansion, magnetostrictive and electroelastic properties, and nonlocal elasticity. The study investigated the effects of various factors on the free vibration of nanobeams, including thermal stress, thermo-magneto-electroelastic coupling, electric and magnetic field potential, nonlocal features, porosity models, and changes in porosity volume. The temperature-dependent mechanical properties of BaTiO3 and CoFe2O4 have been recently explored in the literature for the first time. The dynamics of nanosensor beams are greatly influenced by temperature-dependent characteristics. As the ratios of CoFe2O4 and BaTiO3 in the nanobeam decrease, the dimensionless frequencies decrease and increase, respectively, based on the material grading index. The dimensionless frequencies were influenced by the nonlocal parameter, external electric potential, and temperature, causing them to rise. On the other hand, the slenderness ratio and external magnetic potential caused the frequencies to drop. The porosity volume ratio has different effects on frequencies depending on the porosity model.

This study explores a new nanoplate design’s thermal and mechanical properties, including an auxetic core with a negative Poisson ratio. The core is between face plates made of Barium‐Cobalt, which possess magneto‐electroelastic properties. The analysis centers on the parameters θ, β 1 , and β 2 to clarify their influence on the nanoplate’s performance. The evaluations of the nanoplate’s thermal, electrical, and magnetic properties showcase its remarkable versatility and sensitivity. Incorporating magneto‐electroelastic face plates improves the multifunctionality of the nanoplate, making it a highly promising option for use in smart technologies. The findings offer valuable insights into the distinctive features of auxetic core structures, significantly enhancing the comprehension of these materials. This research emphasizes the potential for creating groundbreaking applications in fields like aerospace engineering and advanced electronics, where versatile and adaptable materials play a vital role. This study contributes to the broader knowledge of auxetic materials and their practical implementation in cutting‐edge technological solutions by exploring the interplay between thermal, mechanical, and magneto‐electroelastic properties.This article is protected by copyright.
