Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]
The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

Research on the Estimation Method of the Stiffness Degeneration Index of Reinforced Concrete Members
Based on variable amplitude displacement cycle tests of 24 reinforced concrete members with different reinforcement conditions, the stiffness degradation index was proposed to describe the damage. The relationship between the stiffness degradation index,

Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure [PDF]
This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method
