Summary:The application of the harmonic acceleration method, which shows some advantages in linear transient vibration analysis compared to the other commonly used methods, is extended to nonlinear problems employing the mode superposition technique and an iteration procedure. Stability analysis shows that the method is unconditionally stable. A higher degree of accuracy is achieved. The efficiency of the method is illustrated by some simple numerical examples.
