ANALYTIC FORMULAE FOR THE CONSTRUCTION OF SYMMETRIC DYNAMICAL SYSTEMS
Kozánek, Jan
In this paper the formulae for complex modal matrix and symmetric regular stiffness matrix and symmetric matrix of viscous damping from real, positive definite mass matrix and from diagonal spectral matrix were deduced. Because of the non-unicity of this problem, the solution is based on the fact, that the helping matrix has the same ratio of the eigenvalues as the inversion of given mass matrix. Finally, the resolvent of this symmetric system was expressed in simple additive form.
