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.

A second question please. I have tried to use the LPM method but my beam segment gets distorted in the configuration where it is connected to other bodies. When I simulate the beam alone, everything works fine. But on connecting to the multibody structure, it gets distorted at the points where the revolute joints are located. What could be responsible? How can I solve? Thanks
I noted the new flexible beam capability in SimScape Multibody. Will there be any more information on how we can implement our own beam models in a similar way? I want to incorporate a nonlinear beam model.
Just a quick question : How can I define the two end points as fixed point ?
very good and helpful for me. thanks
Added R2019a version. Note that Simscape Multibody has a new General Flexible Beam block in R2018b. Contact me for versions compatible with earlier releases.
Added R2018b version. Note that Simscape Multibody has a new General Flexible Beam block in R2018b.
Added link to white paper "Modeling Flexible Bodies with Simscape Multibody"
Added R2018a version. Contact me for earlier releases.
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
