WT5”BZ]:According to the turbine contact problem between the blade root and rotor, the three-dimensional contact surface elements are deduced. For settling the variation and indeterminacy of contact surface, special potential contact elements are used. The incremental loading procedure used is controlled by displacement and stress. The analysis of turbine contact problem between the balde root and rotor in the region in which a ‘push fit’ connects the blade to its rotor is presented. [WT5HZ]
