Substructure analysis with linear constraints using the natural factor formulation
The purpose of this paper is to extend the natural factor substructuring method to include linear, inhomogeneous constraints on the nodal point freedoms. This algorithm, which retains the superior numerical accuracy of the natural factor method, is derived using Lagrange multipliers. A numerical exa...

| description | The purpose of this paper is to extend the natural factor substructuring method to include linear, inhomogeneous constraints on the nodal point freedoms. This algorithm, which retains the superior numerical accuracy of the natural factor method, is derived using Lagrange multipliers. A numerical example illustrates the improvement in accuracy over classical methods. |
