Rat disc torsional mechanics: effect of lumbar and caudal levels and axial compression load [PDF]
The Spine Journal, 2009 Rat models with altered loading are used to study disc degeneration and mechano-transduction. Given the prominent role of mechanics in disc function and degeneration, it is critical to measure mechanical behavior to evaluate changes after model interventions.

Theoretical Framework for Creep Effect Analysis of Axially Loaded Short CFST Columns under High Stress Levels [PDF]
Advances in Civil Engineering, 2020 Due to its excellent mechanical performances, axially loaded concrete‐filled steel circular tube (CFST) columns have been widely used in structural engineering. As an important long‐term behaviour of CFST structures, the creep has an obvious nonlinear property under high stress levels, which makes the influence of creep more complicated. In this study,

Kinematics of a cervical disc prosthesis implanted above or below one- and two-level fusions
North American Spine Society Journal, 2022 Background: The theoretical advantages of hybrid constructs over multi-level fusion have been illustrated in clinical and biomechanical studies. However, there is no biomechanical data on hybrid constructs using load control analyses.

Pre-Load Effect on CFRP-Confinement of Concrete Columns: Experimental and Theoretical Study
Crystals, 2021 The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use of Fiber-Reinforced Polymers (FRPs) has been extensively studied.
