This paper describes a method to vary the flexural bending stiffness of a multi-layered beam. The multi-layered beam comprises a base layer with polymer layers on the upper and lower surfaces, and stiff cover layers. Flexural stiffness variation is based on the concept that when the polymer layer is stiff, the cover layers are strongly coupled to the base beam and the entire multi-layered beam bends as an integral unit. In effect, we have a ‘thick’ beam with contributions from all layers to the… 

Flexural Stiffness Control of Multilayered Beams

This paper focuses on the ability to introduce change in the flexural bending stiffness of a niultilayered beam. The multilayered beam comprises a base layer with polymer layers on the upper and
