Piezomagnetic Behavior of Functionally Graded Cylinders under Non-Axisymmetric Hygrothermal Loading: Interplay between Loading Contribution, Material Properties, and Elastic Response

This study investigates the piezomagnetic behavior of functionally graded cylinders under non-axisymmetric hygrothermal conditions using an analytical approach. The cylinders are subjected to internal pressure, magnetic potential, moisture concentration, and thermal loading, which significantly impact their mechanical response. We examine the effects of loading contributions on the elastic response of piezomagnetic functionally graded materials (FGMs), focusing on the intricate interplay between material properties and environmental conditions. The von Mises stress, maximum shear stress, and equivalent magnetic induction components are analyzed to elucidate the complex interactions between the loadings. Our findings indicate that internal pressure has a dominant influence on stress distribution, with moisture concentration and thermal effects introducing complexity to the stress relationships. Although the magnetic field’s impact may be less pronounced compared to other forces and conditions, its effect on magnetic induction components is significant and as expected. Our results provide valuable insights into the design and optimization of piezomagnetic FGMs for various engineering applications that involve exposure to non-axisymmetric hygrothermal environments.
