Some properties of the FEM applied on structures with random imperfections
Náprstek, Jiří
Numerical analysis of thin walled systems using FEM can be based on the Arc Length Method or on simulations supported by Bayesian algorithm of posterior probabilities.
Flutter instability due to nonconservative and gyroscopic forces
Náprstek, Jiří
Theoretical explanation of a flutter effect as a stabilityloss of a slender beam response due to its aeroelasticinteraction with an air stream.
Aeroelastic instability of a system with nonconservativeand gyroscopic forces
Náprstek, Jiří ; Pospíšil, Stanislav
Mathematical model of stability loss due to flutter effect.The origin of instability consists of nonconservative andgyroscopic forces.

Stability Assessment of Flutter - Type Vibration Using Lyapunov Function
Náprstek, Jiří
The paper deals with the problem of bending torsional flutter of a slender beam of rectangular cross section.
Resonance Speeds of Axle Forces Row Moving along a Beam
Náprstek, Jiří
The railway bridges of small and medium spans have shownthe vibrations of resonance character which could be caused by high speed trains with their great number of axles inregular distances.
