.... The objective of this computational study was to investigate the effects of nucleus swelling on disc geometry, fiber orientation, and mechanical behavior by comparing those of prestrained and zero-pressure (unswelled) discs. Thermoelastic analysis techniques were repurposed in order to determine the zero...

... a constitutive model for modeling arterial layers with distributed collagen fiber orientations as follows: 2 U = C 10 ( I ¯ 1 - 3 ) + 1 D [ ( J el ) 2 - 1 2 - ln J el ] + κ 1 2 κ 2 ∑ α = 1 N...

... studies. Porcine condylar cartilage was tested under uniaxial tension in two directions, anteroposterior and mediolateral, with three regions per direction. Stress relaxation behavior was modeled using the Kelvin model and a second-order generalized Kelvin model, and collagen fiber orientation...
