This study analyzes the asymptotic behavior of thin magnetoelastic shallow shells using Gamma-convergence. It incorporates geometric effects from vanishing curvature, generalizing previous work.
Area of Science:
- Solid Mechanics
- Continuum Mechanics
- Mathematical Physics
Background:
- Magnetoelasticity describes the interplay between magnetic fields and mechanical deformation in materials.
- Shallow shell theory simplifies the analysis of thin structures with small deflections.
- Gamma-convergence is a mathematical tool for analyzing the limiting behavior of energies.
Purpose of the Study:
