“…4. The simulated results for distribution of fluid pressure are consistent with the experimental findings [53]. At the initial condition (no load), the fluid pressure in the NP is about 0.40 MPa, which is generated due to the higher osmolarity in the disk than that in the ambient environment, and the pressure is equilibrated by the tension of solid matrix.…”

“…The fluid pressure decreases to 1.18 MPa after 4 hrs of creep test. McNally and Arridge [53] reported that the fluid pressure is about 1.70 MPa in a healthy L4-5 disk under 1392 N compressive load. By linearly scaling the fluid pressure with the fraction of compressive loads, the fluid pressure under 1000 N compressive load in the experiment would be 1.22 MPa, which is close to our simulated fluid pressure in the NP (1.18-1.33 MPa).…”

“…Stretching of the annulus fibresmay occur underthe application of tensile forces to the annulus or through the hydrostaticpressure exertedbythe nucleus on the annulus under axiall oads (7, 20-22). Undert he application of bending moments (flexion, exten-sion, or lateralbending),the fibresofthe annulus arecompressed towards the direction of the bending,whereas in the opposite direction,the fibresare in tension (20,23,24). The discf ibres ares tretchedi nt he compressed region because of disc bulgingdue to hydrostaticpressure of the nucleus pulposusand in the tensileregion because of direct tensile forces acting on the annulus fibrosus (21,22).…”

“…Among the few published analytical studies, there are those based on the theory of thick-walled cylinders (Hickey and Hukins, 1980, Hukins, 1992, PrudHomme, 2008, the thin-shell theory (Demers et al, 2013, McNally andArridge, 1995), the theory of laminated plates (Iatridis and ap Gwynn, 2004) and force equilibrium in a series of fiber sheets (Ngwa and Agyingi, 2011). Analytical modeling may appear restrictive to simulate biomechanical tissues, but is yet promising for modeling IVDs, particularly using thin-shell theory.…”
