Abstract
Geometrically Exact Beam Theory (GEBT), is a general-purpose tool for nonlinear analysis of composite slender structures, meeting the design challenges associated with future engineering systems featuring highly-flexible slender structures made of composites. GEBT is based on the mixed formulation of the geometric exact beam theory which can capture all geometric nonlinearities due to large deflections and rotations, subject to the strains being small. Coupled with Variational Beam Sectional Analysis (VABS), a general-purpose cross-sectional analysis, GEBT can effectively analyze geometric nonlinear behavior of slender structures having arbitrary cross-sections made of arbitrary materials.
Currently no GUI is available for this tool, first you need to map webdav as a network drive according to the instruction given in the knowledge. Then put gebt inputs files into that drive. Then you can directly type gebt input_file to execute the code. If you put all your files in a directory, say gebtdata, then you need to type cd gebtdata, then type gebt input_file to execute the code.Please refer to the user manual regarding how to prepare input file for GEBT. Several examples are provided in the examples.ppt file along with the input files in examples.zip
