GEBT
A General-Purpose Nonlinear Composite Beam Code
Target Applications
Introduction
GEBT (Geometrically Exact Beam Theory) is a code implementing the mixed variational formulation of the geometrically exact intrinsic beam theory developed by Prof. Hodges of Georgia Institute of Technology, which captures all the geometrical nonlinearities obtainable by a beam model. It is a companion code of VABS, a general-purpose cross-sectional analysis tool, to enable efficient yet high-fidelity analysis of slender structures, whether they are made of composites or not. The details of GEBT functionalities can be found in the accompanion user manual.
Development of GEBT was initiated in the summer of year 2008 at AFRL/RB support by a summer faculty fellowship, later significantly enhanced when Prof. Yu was spending his sabbatical at AFRL/RB. Dr. Maxwell Blair of AFRL/RBSD has been a very strong advocate of this code due to its potential application in USAF applications with highly flexible structural components. The code is written in Fortran 90/95 and designed for straightforward integration with other codes. The code is a freeware for anybody who requests. The performance and robustness of code will be continuously improved based on feedback from its users.
