Notably, this change in traction rate and contraction velocity happens nearly instantaneously (within 0.5 s) (FIG. 4B inset), indicating that cells can reversibly respond to a stiffness cue on a whole cell level on a timescale of seconds.
18 In agreement with this report, our findings on the range of overall maximum forces indicate a similar maximum force exerted by cells that were seeded on pillars with a stiffness of approximately 15 nN/μm.
In this study, the vertical dynamic stiffness of fasteners in installation faults was measured based on a dynamic stiffness test by means of an experimental apparatus that was devised to feasibly reproduce installation faults with an arbitrary shape.
In this paper, a modified model is developed based on a residual stiffness and strength model.
The prediction of the post-buckling compressive strength is performed by a progressive failure analysis which was developed based on a progressive stiffness degradation model and a nonlinear finite element analysis with a new explicit through-thickness integration scheme.
22 The four health states applied in the model were based on a morning stiffness duration of less than 1 hour, 1 2 hours, 2 3 hours, and $3 hours.
In view of engineering analyses of structural components, an anisotropic constitutive model in average stresses and strains is selected, centered on an elastic stiffness tensor and on an elastic limit locus and a strength locus in the average stress space.
The DPSCs on a high-stiffness three-dimensional (3D) nanofibrous gelatin (NF-gelatin) scaffold had more organized cytoskeletons and a larger spreading area than on a low-stiffness NF-gelatin scaffold.
The working surface was suspended on a negative-stiffness passive vibration isolation platform (MinusK Technology 250BA-1, www.comusk.com).com
