Possible WLC Models for Three-Dimensional Entropic Elasticity
Professor Ray W. Ogden and his colleagues published a critical review on how to extend the worm-like chain (WLC) model to three-dimensional elasticity.

The WLC model, e.g. Marko and Siggia, Macromolecules, 28, 8759-8770, is an elastic beam model. Its successful modeling of DNA has been a triumph for entropic elasticity theory.
