Abstract
This chapter presents a nonlinear finite element approach for modeling nano and macroscale beam-like materials and structures. The work is based on a series of three articles published by the author and his co-workers from 2007 to 2010 (Leamy 2007; Leamy and Lee 2009; Leamy 2010). The chapter begins by describing a finite element procedure for discretizing a set of nonlinear, intrinsic beam equations. These equations are notable for their use of curvature and strain, vice rotational and displacement, field variables. Included in the finite element development is a discussion of zero energy modes and their remediation. Attention then turns to application of the approach in studying dynamics of systems at the nanoscale (e.g., carbon nanotubes) through to the macroscale (e.g., helical springs).
