Magnetoelasticity combines two different phenomena of magnetism and elasticity and in this thesis it is studied in a polymer gel material.
Polymer gels are soft materials and when they are embedded with colloidal size magnetic particles they respond to externally applied magnetic fields and exhibit various deformation modes. In this thesis the magnetoelasticity of gels is studies from the three fronts of theory,
computation and experiment to clearly demarcate the realms of the same. The behavior of the magnetoelastic gel is studied using the principle of energy minimization. The inputs for this theoretical work come from the extension of the micromagnetics theory. Numerical algorithms have been developed that computationally implement the energy minimization in magnetoelastic gel. For the experimental magnetoelasticity the strong particle size effect that was observed from the computational predictions is validated.
