Piezoelectric stress analysis of a composite disk under parabolic temperature distribution using a Pasternak foundation model

This study delves into the intricate interplay between the piezoelectric effect and thermal loading on the elastic stress distribution within a composite disk reinforced with steel fibers. By employing the Pasternak foundation model, we capture the complex interactions between the disk and its supporting medium, enhancing the realism of our analysis. The research focuses on a parabolic temperature distribution, a common scenario in various engineering applications. Analytical solutions are derived to determine the radial and tangential stresses within the disk under different thermal conditions. Through a comparative analysis, we elucidate the significant impact of temperature gradients on the stress distribution, highlighting the role of the piezoelectric effect in mitigating or amplifying these stresses. The findings of this study offer valuable insights for the design and optimization of advanced structural components, such as those used in aerospace, automotive, and energy harvesting applications, where thermal and electrical considerations are paramount.
