The buckling of magneto-strictive Cosserat rods

D. Sinden & G.H.M. van der Heijden

Magneto-striction is a property of ferromagnetic materials which causes them to change their shape or dimensions during the process of magnetization. A conducting ferromagnetic rod in a magnetic field will experience a Lorentz body force and change size, coupling the effective material properties to the loading conditions. Homoclinic solutions, relating to localised post-buckled configurations, and the post-buckling curves are computed, illustrating the influence of magnetostriction on the post-buckling behaviour.
