elementmodel. In this paper an alternative approach of directly comparing themass,stiffness, and dampingmatricesof the dynamic model is explored. A new algorithm which estimates themass,stiffness, and dampingmatricesof a structure from Frequency Response Function (FRF) measurements is also presented.stiffnessmatrix: found. The fixed end reaction force and the reaction moment are assumed to be acting upwards and counterclockwise, respectively. Now use.
