Bending instabilities of soft biological tissues

Abstract: a b s t r a c tRubber components and soft biological tissues are often subjected to large bending deformations while ''in service". The circumferential line elements on the inner face of a bent block can contract up to a certain critical stretch ratio k cr (say) before bifurcation occurs and axial creases appear. For several models used to describe rubber, it is found that k cr ¼ 0:56, allowing for a 44% contraction. For models used to describe arteries it is found, somewhat surprisingly, that the strain-stiff… Show more

“…Recalling the boundary condition AE s ðr o Þ ¼ 0, it is possible to define a functional dependence between the traction and the displacement amplitudes as r 2 AE s ¼ Z s U s , where Z s is the conditional impedance matrix, with Z s ðr o Þ ¼ 0 [28]. Therefore, it is possible to use Z s in Eq.…”

“…Optimal here is used in the sense that an efficient numerical procedure can be implemented in order to solve the incremental problem [32,34,24]. The hermitian property, also implies that the matrix iÎG is symmetric, whereÎ is defined as the block matrix with 0-blocks on the diagonal and identity blocks elsewhere.…”
