Abstract

Based upon a combination of a temporally-piecewise adaptive algorithm with an Element-Free Galerkin Scaled Boundary Method (EFG-SBM), a partitioning algorithm is presented for the two-dimensional viscoelastic analysis of cyclically symmetric structures. By expanding variables at a discretized time interval, the variations of variables can be described more precisely, and a space–time domain-coupled problem can be converted into a series of recurrent boundary value problems which are solved by an EFG-SBM-based partitioning algorithm via an adaptive computing process. Numerical examples are given to verify the proposed algorithm in terms of computing accuracy and efficiency.
