Thin walled beams - Wikipedia

In structural engineering and mechanical engineering, generalised beam theory (GBT) is a one-dimensional theory used to mathematically model how beams bend and twist under various loads. It is a generalization of classical Euler–Bernoulli beam theory that approximates a beam as an assembly of thin-walled … See more Its origin is due to Richard Schardt (1966). Since then many other authors have extended the initial (first-order elastic) GBT formulations developed by Schardt and his co-workers. Many extensions and applications of GBT … See more The theory can be applied without restrictions to any prismatic thin-walled structural member exhibiting straight or curved axial axis (any loading, any cross-section geometry, … See more WebA uniform beam element of open thin-walled cross-section is studied under stationary harmonic end excitation.
