Abstract
Numerical experiences reveal that the dynamic relaxation (DR) method performances are related to the structural types. This paper is devoted to compare the DR schemes for geometric nonlinear analysis of shells. To achieve this task, twelve famous approaches are introduced briefly. The differences of these schemes are on the estimation of the time step, the mass and the damping matrices. In this study, several benchmark structures are analyzed by using these twelve techniques. Based on the number of iterations and the analysis duration, their performances are graded. Numerical findings reveal the high efficiency of the kinetic dynamic relaxation (kdDR) approach and the Underwood's strategy.
