Acoustic displacement triangle based on the individual element test [PDF]
Latin American Journal of Solids and Structures, 2012 A three node -displacement based- acoustic element is developed. In order to avoid spurious rotational modes, a higher order stiffness is introduced. This higher order stiffness is developed from an incompatible strain field which computes element volume

Post-traumatic elbow rotational stiffness. [PDF]
Shoulder Elbow, 2014 Background The elbow is an important but complex structure, with movement in both the sagittal plane in flexion and extension, as well as the rotational plane in forearm supination and pronation. Trauma is a common cause of elbow stiffness, which significantly hampers daily function.

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

Analysis of Rotational Stiffness of the Timber Frame Connection [PDF]
Sustainability, 2020 Initially, timber was considered only as an easily accessible and processable material in nature; however, its excellent properties have since become better understood. During the discovery of new building materials and thanks to new technological development processes, industrial processing technologies and gradually drastically decreasing forest ...

Shoulder stiffness and rotator cuff repair [PDF]
British Medical Bulletin, 2012 Shoulder stiffness is a frequent complication of surgical repair of rotator cuff tears. Post-operative stiffness negatively affects surgical outcomes leading to a substantial comorbidity and to the failure of surgical treatment. Also, a stiff shoulder could commonly be concomitant with an rotator cuff tear (RCT).We performed a comprehensive search of ...

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.
