Analysis of a dynamic peeling test with speed-dependent toughness

Lazzaroni, Giuliano; Nardini, Lorenzo (2017)

We analyse a one-dimensional model of dynamic debonding for a thin film, where the local toughness of the glue between the film and the substrate also depends on the debonding speed. The wave equation on the debonded ...
Existence and uniqueness of dynamic evolutions for a one dimensional debonding model with damping

Riva, Filippo; Nardini, Lorenzo (2018-07-16)

In this paper we analyse a one-dimensional debonding model for a thin film peeled from a substrate when friction is taken into account. It is described by the weakly damped wave equation whose domain, the debonded region, ...
On the 1D wave equation in time-dependent domains and the problem of debond initiation

Lazzaroni, Giuliano; Nardini, Lorenzo (SISSA, 2017)

Motivated by a debonding model for a thin film peeled from a substrate, we analyse the one-dimensional wave equation, in a time-dependent domain which is degenerate at the initial time. In the first part of the paper we ...
