A new expression to predict secant rotational stiffness of spudcan in undrained soils [PDF]
E3S Web of Conferences, 2021 The nonlinear behavior of spudcan foundation will lead to the decrease of the rotational stiffness of the spudcan, leading to the increase of the stress at the critical member of the offshore jack-up drilling platform. Secant rotational stiffness is used

Post Buckling Behavior of Prismatic Structural Steel Members with Semi Rigid Connections [PDF]
Engineering and Technology Journal, 2016 In most designs of steel frames,beam-column connections are assumed either perfectly pinned or fully rigid. This assumption results in an incorrect estimation of the structural behavior of these frames.

Design and Analysis of Variable-Stiffness Fast-Steering Mirror
Actuators, 2023 The non-variable stiffness of the flexible hinge in the fast-steering mirror (FSM) cannot adapt to varying load demands. To address this issue, this paper presents an innovative variable-stiffness rotational mechanism designed for use with FSMs. Firstly,

Negative potential energy content analysis in cracked rotors whirl response
Scientific Reports, 2021 Appearance of transverse cracks in rotor systems mainly affects their stiffness content. The stability of such systems at steady-state running is usually analyzed by using the Floquet’s theory.

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.
