Geometrically nonlinear theory of thin-walled composite box beams using shear-deformable beam theory [PDF]

, 2009
A general geometrically nonlinear model for thin-walled composite space beams with arbitrary lay-ups under various types of loadings is presented. This model is based on the first-order shear deformable beam theory, and accounts for all the structural ...

Left Ventricular Torsion Associated With Aortic Stiffness in Hypertension

Journal of the American Heart Association, 2018
Background Left ventricular (LV) torsion plays a key role in cardiac efficiency. In hypertension, aortic stiffening augments cardiac afterload. However, little is known about the links between LV regional contraction and aortic stiffness.

Detachment of semiflexible polymer chains from a substrate - a Molecular Dynamics investigation

, 2014
Using Molecular Dynamics simulations, we study the force-induced detachment of a coarse-grained model polymer chain from an adhesive substrate. One of the chain ends is thereby pulled at constant speed off the attractive substrate and the resulting saw ...
