Thermo-Magneto-Elastic-Plastic Analysis of Functionally Magnetoelastic Pressurized Thick Cylindrical Structure.

This article explores a semi-analytical method for the Thermo-Magneto-Elastic-Plastic analysis of functionally magnetoelastic (FM) thick cylinders. The FM cylinder is subjected to a uniform magnetic field and combined pressure and temperature loads. Material properties vary radially according to a power-law distribution. The elastic and elastic-plastic distribution of stresses and radial displacement through the radius are obtained. Also, Tresca's yield criterion is used to describe material behavior in plastic zone. The effects of the grading index (β), pressure, temperature, and magnetic intensity vector are discussed. The results indicate that increasing the value of β, internal pressure, external temperature, and magnetic intensity vector lead to the expansion of the yield point from the inner to the outer surface.
