Rotational and peak torque stiffness of rugby shoes
The Foot, 2014 Sports people always strive to avoid injury. Sports shoe designs in many sports have been shown to affect traction and injury rates. The aim of this study is to demonstrate the differing stiffness and torque in rugby boots that are designed for the same effect.Five different types of rugby shoes commonly worn by scrum forwards were laboratory tested ...

Web rotational stiffness of continuous steel-concrete composite castellated beams
Fracture and Structural Integrity, 2019 Continuous composite beams can present a global instability known as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment is ...

A novel energy-efficient rotational variable stiffness actuator [PDF]
2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011 This paper presents the working principle, the design and realization of a novel rotational variable stiffness actuator, whose stiffness can be varied independently of its output angular position. This actuator is energy-efficient, meaning that the stiffness of the actuator can be varied by keeping constant the internal stored energy of the actuator ...

Numerical Studies of the Rotational Stiffness of Purlin–Sheeting System [PDF]
, 2018 In light-gauged steel purlin-to-sheeting roof systems, the attached sheeting can provide rotational restraints to the purlin. The magnitude of the additional rotational stiffness offered by the sheeting will affect the load bearing capacity of the purlin.

Influence of rotary flexibility of joints on the statics and dynamics of the arch structures [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2023 The paper presents arch structures modeled by finite elements in which the nodes can be flexibly connected. Two-node curved elements with three degrees of freedom at each node were used.
