This file contains flexible beam models implemented in Simscape Multibody that use lumped parameter and finite element data approaches. It includes methods to compute static deflection, natural frequencies, plot mode shapes, and obtain the state-space representation from lumped parameter model.
Please read the README.txt file to get started.

Adjusted script sm_flex_body_lib_lpar_construct_beam.m for more compact layout of flexible elements on the block diagram.
Adjusted parameterization for structural damping. Changes made to R2017b, R2017a, and R2016b versions. Contact me for releases R2016b and earlier.
Complete overhaul of libraries and examples, using new method for finite element approach. Includes R2017a and R2017b versions.
Added R2017a version and text for citing submission in other works. Latest version allows beams of circular and arbitrary cross section, and includes more documentation. Made startup script compatible with Mac.
Added version for R2016a.
I have added Control System Toolbox in the list of required products.
Have uploaded Flexible_Beam_State_Space_Approach_PDF.pdf
