Improved dynamic structural analysis for linear and nonlinear systems

A new family of higher-order implicit, one-step integration algorithms has been developed and evaluated with respect to stability, accuracy, convergence, dissipation, dispersion and overshoot behavior. These algorithms have minimum order of accuracy two, and maximum order of accuracy four. In general, they have order of accuracy three. All the algorithms are unconditionally stable, do not overshoot in displacements or in velocities and possess desirable numerical dissipation which can be continuously controlled. In particular, these schemes possess better dissipative and dispersive characteristics than the commonly used second-order methods.
