Abstract

Fully intrinsic equations are used to obtain a model compliant with Euler-Bernoulli assumptions for a beam under a linearly distributed follower force known as a Hauger column. The advantage of the intrinsic formulation in modeling problems with non-conservative forces is discussed here. Only intrin...
