Nonlinear dynamic FE analysis of structures consisting of rigid and deformable parts II-Computer implementation and test examples

This is the second part of the paper(Rojek and Kleiber 1993) devoted to nonlinear dynamic analysis of structures consisting of rigid and deformable part. The first part contains a theoretical formulation of nonlinear equations of motion for the coupled system as well as a solution algorithm. The second part presents the computer implementation of the equations derived in the first part with a short review of the capabilities of the computer program used and the library of finite elements. Details of material nonlinearity treatment are also given. The paper is illustrated by discussing a practical problem of a safety cab analysis for an agricultural tractor.
