An experimental study of the magnetoelastic postbuckling behavior of a beam: An investigation of the dependency of the buckling field upon the misalignment of a uniform, transverse magnetic field and the normal to a ferromagnetic cantilever beam

摘要: The results of an experimental investigation the postbuckling behavior a ferromagnetic cantilever beam in transverse magnetic field are presented. A description apparatus and technique used to cancel effect initial curvature other invevitable imperfections by systematically varying misalignment normal discussed. For each misalignment, buckling is measured. plot vs. has usual cusp rapid decline with increasing imperfection that come be associated imperfection-sensitive structures. Previous theoretical predictions found good qualitative agreement results. Possible explanations for quantitative differences between sources error
