Endoscope having flexible tube


Endoscope having flexible tube

Date/App# patent app List of recent Stiffness-related patents
 Computationally efficient nonlinear structural analysis patent thumbnailnew patent Computationally efficient nonlinear structural analysis
Seismic displacement demands for design of a bridge frame structure are typically determined from linear-elastic analysis (lea), which are often incorrect, and compared to displacement capacity from a nonlinear pushover analysis. Nonlinear time-history analysis (ntha) provides the most realistic assessment of displacement demands because it properly models the physics of the dynamic problem, wherein stiffness of the bridge varies over time.
