Abstract

It is shown that centrifugal stiffening effects in rotating beams can be countered by spanwise stiffness variation for a given mode. Smart materials such as magnetorheological elastomer can be used to vary the stiffness in a manner such that a given mode is destiffened. The flexural stiffness functions are demonstrated using a p-version finite element rotating beam code and represent a multifunctional rotating structure concept which can be used for active stiffness control.
