Through the pseudo-static test on the steel truss coupling beams with buckling-restrained brace, the bearing capacity, deformation capacity, hysteresis curve, skeleton curve, ductility, Energy Dissipation and stiffness degradation of such coupling beam are understood. The test results show that the steel truss coupling beams with buckling-restrained brace is characterized by bigger bearing capa...

Original scientific paper Fluidic Muscle produced by Festo Company is the most used and investigated type of pneumatic artificial muscle (PAM) actuators which can be characterized such as powerful, dynamic (even 6000 N, 50 m/s), judder-free and resistant to dirt and dust, therefore these actuators are widely used in industrial environment besides electric motors or hydraulic actuators. One of t...

Hysteresis of a piezoelectric actuator is ratedependent. Most hysteresis models are based on elementary rate-independent operators and are not suitable for modeling actuator behavior across a wide frequency band. This work proposes a rate-dependent modified PrandtlIshlinskii (PI) operator to account for the hysteresis of a piezoelectric actuator at varying frequency. We have shown experimentall...

The relationship between concentration c and discharge Q in a stream is one of the aspects of hydrochemical catchment response that has been used widely as a diagnostic. In particular, loops in the c–Q curve, commonly referred to as hysteresis loops, are used to infer particular mixing patterns. At the South Fork of Brokenback Run (SFBR) in the Shenandoah National Park, Virginia, we have eviden...

A recent paper [Physical Review B 64 014508 (2001)] claims to present an exact method to extract the critical current density J C from the M-H hysteresis curve. We show that this claim appears unjustified.

Flood dynamics of large lake floodplain systems are typically complex. This paper analyses the characteristics and factors that influence the hysteresis of water area–stage curves for Poyang Lake, the largest freshwater lake in China characterized by complex geomorphology and upstream–downstream exchange conditions. For this purpose, a two-dimensional hydrodynamic model (EFDC) based on seven sc...
