Analytical modeling of reinforced concrete columns subjected to bidirectional shear [PDF]
, 2017 Under general seismic loading, reinforced concrete columns may be subjected to lateral loads in more than one direction. Available experimental data on columns subjected to bidirectional forces indicate that higher levels of damage and a higher loss of ...

On mechanical properties of planar flexure hinges of compliant mechanisms [PDF]
Mechanical Sciences, 2011 The synthesis of compliant mechanisms yield optimized topologies that combine several stiff parts with highly elastic flexure hinges. The hinges are often represented in finite element analysis by a single node (one-node hinge) leaving doubts on the ...

Approximate equations for circular hinge stiffnesses
Nihon Kikai Gakkai ronbunshu, 2023 Flexure hinges are widely used for very high precision mechanisms, such as a high precision linear guide, a nano positioning stage, a robot hand and etc., because of no gap and no friction. Regarding circular hinge stiffnesses, Paros and Weisbord derived

Research on a Novel Flexure Hinge [PDF]
Journal of Physics: Conference Series, 2006 A novel single axis flexure hinge named hyperbolic flexure hinge is introduced as new designs in two-dimensional monolithic mechanisms. Based on the Castigliano's second theorem, Closed-form equations are formulated for compliances to characterize both the active rotation and all other parasitic motions.
