Modified Predictor-Corrector Method in Structural Dynamics

An explicit numerical integration method is applied on structural dynamics problems. The method is based on the relationship that m-step Adams-Moulton method is linear convex combination of the (m−1)-step Adams-Moulton andm-step Adams-Bashforth method with a fixed weighting coefficients [1]. A general form is used to evaluate the recurrence expressions using the different number of previous mesh points. The analytical upper bound of modified predictor-corrector method is given in the closed form [2]. The expressed order of convergence is now m+2. The explicit numerical algorithm is given for modified 3-step predictor-corrector method.
