Structural Dynamics : Using FE Methods
Those who have meditated on the beauty and utility of the general method of Lagrange – who have felt the power and dignity of that central dynamical theorem which he deduced from a combination of the principle of virtual velocities with the principle of D’Alembert – and who have appreciated the simplicity and harmony which he introduced by the idea of the variation of parameters, must feel the ...
متن کاملParallel Modal Synthesis Methods in Structural Dynamics
Within the finite element framework, we deal with large-scale eigenvalue problems induced by free vibration analysis of complex structures. The classical approach for the solution of such problems consists first of reducing the number of unknowns, allowing to reduce the computational cost of eigensolver, because only the lowest eigenfrequencies are classically researched in modal analysis. Comp...
متن کاملTime Finite Element Methods for Structural Dynamics
Time finite element methods are developed for the equations of structural dynamics. The approach employs the time-discontinuous Galerkin method and incorporates stabilizing terms having least-squares form. These enable a general convergence theorem to be proved in a norm stronger than the energy norm. Results are presented from finite difference analyses of the time-discontinuous Galerkin and l...
