Many essential phenomena in biology involve changes in cell shape. Cell deformation occurs in response to physical forces either coming from the external environment or intracellularly generated. In most tests of cell rheology, an external constraint is usually superimposed on an already mechanically active cell, thus the measurements may reflect both active motion and passive viscoelastic defo...

The objective of the this research paper is to predict the deformation length of glass/epoxy composite laminates using Finite Element Analysis (FEA) and compare with the Universal Testing Machine (UTM) deformation results through the tensile load. The laminate was made by six layered glass fiber (in woven mat form) with epoxy as the binding medium by hand lay-up technique, cured at room tempera...

By means of extensive contact dynamics simulations, we investigate the mechanical equilibrium and deformation of a granular material composed of irregular polyhedral particles confined between two horizontal frictional planes. We show that, as a consequence of mobilized wall-particle friction forces at the top and bottom boundaries, the transient deformation induced by a constant vertical load ...

Direct measurements of muscular forces usually require a substantial rearrangement of the biomechanical system. To circumvent this problem, various indirect techniques have been used in the past. We introduce a novel direct method, using a lightweight (~0.5 g) miniature (3 x 3 x 7 mm) in-line load-cell to measure tension in the tibialis anterior tendon of rats. A linear motor was used to produc...

It is vital that cells respond rapidly to mechanical cues within their microenvironment through changes in cell shape and volume, which rely upon the mechanical properties of cells' highly interconnected cytoskeletal networks and intracellular fluid redistributions. While previous research has largely investigated deformation mechanics, we now focus on the immediate cell-shape recovery response...

The creep anisotropy of nickel-base superalloys with a cubic y' morphology is studied with a composite model. Creep curves and the internal stress distribution in the microstructure under [Oll] load are calculated with a Finite Element Procedure. Analytical considerations are made for arbitrary loading directions. y' cubes (with their interfaces aligned parallel to (001) planes) under [OOl] loa...
