Abstract

An explicit predictor–corrector algorithm is derived from the implicit α-method. This explicit algorithm is shown to have better stability and accuracy properties than its Newmark-based predecessor. This algorithm is then combined with the implicit α-method, resulting in an implicit–explicit α-method which can be effectively utilized for linear and non-linear structural dynamics calculations.
