ABSTRACT:
A method of analyzing a structure containing a rigid body. The method defines a set of displacement factors to be imposed on a structure model. The method is used for calculating structure stress defining equations including a load vector representing externally applied forces on the structure model. The method modifies the load vector to compensate for rigid body deformation and evaluates stresses on the structure model from data generated from the structure stress defining equations.
