Nonlinear morphoelastic plates II: Exodus to buckled states [PDF]

Mathematics and Mechanics of Solids, 2011
Morphoelasticity is the theory of growing elastic materials. The theory is based on the multiplicative decomposition of the deformation gradient and provides a formulation of the deformation and stresses induced by growth. Following a companion paper, a general theory of growing non-linear elastic Kirchhoff plate is described.

Analytical and numerical investigations of the collapse of blood vessels with nonlinear wall material embedded in nonlinear soft tissues

Alexandria Engineering Journal, 2018
In this paper, shapes of nonlinear blood vessels, surrounded by nonlinear soft tissues, and buckled due to radial pressure are solved for analytically and numerically. The blood flow rates through the bucked shapes are then computed numerically.
