Application of the substructuring technique to non-linear dynamic structural analysis

The use of the substructuring technique for the solution of two-dimensional non-linear problems of dynamic response with the direct time integration method is examined. The object is to develop schemes that can considerably reduce the computational expense in analyses of locally and fully non-linear dynamic problems as compared with a traditional analysis. After a review of the principle of the incremental equilibrium equations of motion, some practical illustrations of the technique are dealt with in detail. A specific flow chart is proposed and a number of numerical examples are presented.
