...Simon Chesne; Charles Pezerat; Jean-Louis Guyader This work deals with the identification of forces at plate boundaries, by measuring displacements only. Shear force and bending moment directly depend on different spatial derivatives of displacement at plate boundaries that can be approximated from...

... for nonlinear system identification, in the absence of an input measurement, is presented that uses information about the nonlinear elements of the system to estimate the underlying linear parameters. Restoring force, boundary perturbation, and direct parameter estimation techniques are combined to develop...

.... When only leakage prediction is required, an axisymmetric model is created. To calculate rotordynamic forces, a full 3D, eccentric model is solved. The results demonstrate improved leakage and rotordynamic prediction over bulk-flow approaches compared to experimental measurements. Contributed...

... an instantaneous impulsive force on the buoy, analogous to the impact of a ball bouncing on a rigid surface. The magnitude of the axial component of the velocity is reduced at this time. Fluid inertia and damping are not included, and the wave forces are assumed to be harmonic. The effects of the coefficient...

...Adam D. Stelzner, Senior Staff; Daniel C. Kammer, Associate Professor; Paul Milenkovic, Associate Professor A new method for the estimation of forces applied to a structure is presented. This time domain technique uses the structures response time history and returns an estimate of the applied...

...X. Q. Zhu, Graduate Student; S. S. Law, Associate Professor A method is presented to identify indirectly loads moving on an orthotropic plate. The loads are in a group of two forces or four forces. The dynamic behavior of the plate under the action of these moving loads is analyzed. A method...
