Mathematical justification of a viscoelastic elliptic membrane problem
G. Castiñeira, Á. Rodŕıguez-Arós · Comptes Rendus Mécanique · 2017
We consider a family of linearly viscoelastic elliptic shells, and we use asymptotic analysis to justify that what we have identified as the two-dimensional viscoelastic elliptic membrane problem is an accurate approximation when the thickness of the shell tends to zero. Most noticeable is that the limit problem includes a long-term memory that takes into account the previous history of deformations. We provide convergence results which justify our asymptotic approach.
