Sorted by: Date Added To NTRS in Descending order A simplified orthotropic formulation of the viscoplasticity theory based on overstress Author(s): Sutcu, M.; Krempl, E. Abstract: An orthotropic, small strain viscoplasticity theory based on overstress is presented. In each preferred direction the stress is composed of time (rate) independent (or plastic) and viscous (or rate dependent) contributions. ... NASA Center: NASA (non Center Specific) Publication Year: 1988 Added to NTRS: 2008-05-30 Accession Number: 88N21505; Document ID: 19880012121 The influence of Coriolis forces on gyroscopic motion of spinning blades Author(s): Sisto, F.; Chang, A.; Sutcu, M. Abstract: Turbomachine blades on spinning and precessing rotors experience gyroscopically induced instabilities and forcing. With vehicle-mounted turbomachines, either constant or harmonic precession occurs, depending on vehicle or ...

Abstract: The viscoplasticity theory based on overstress, a simplified version of Sutcu (1985) theory, is presented for the case of orthotropy. The theory permits asymptotic solutions for checking numerical experiments and for ...
