 double chrono::fea::AverageSectionParameters::artificial_factor_for_shear_damping

An artificial factor to modify the damping coefficient in the shear deformation, which may be helpful to improve the numerical stability of Timoshenko beam.

But you need to take care of the final structural damping ratio of your model after assigning this factor.
