Dynamics of Materials with a Deformability Threshold

Angiolo Farina, Antonio Fasano, Lorenzo Fusi, K. R. Rajagopal


Some biological tissues exhibit a sharp reduction of deformability beyond some stress
threshold, below which they may be considered elastic. This behaviour can be seen as a
limit situation in which the material becomes undeformable beyond some deformation threshold.
As a model problem we have considered the motion of a layer of such a material in which one
boundary is kept fixed while to the other a tangential stress beyond threshold is applied.
The corresponding mathematical model is formulated as a hyperbolic free boundary problem in
which at each time instant the interface is made of the points reaching the threshold stretching.
