In this paper we deal with a debonding model for a thin film in dimension two, where the wave equation on a time-dependent domain is coupled with a flow rule (Griffith's principle) for the evolution of the domain. We propose a general definition of energy release rate, which is central in the formulation of Griffith's criterion. Next, by means of an existence result, we show that such definition is well posed in the special case of radial solutions, which allows us to employ representation… Expand

In this paper we address the problem of continuous dependence on initial and boundary data for a one-dimensional dynamic debonding model describing a thin film peeled away from a substrate. TheExpand
Existence and uniqueness of dynamic evolutions for a one-dimensional debonding model with damping
In this paper we analyse a one-dimensional debonding model when viscosity is taken into account. It is described by the weakly damped wave equation whose domain, the debonded region, grows accordingExpand
On the 1d wave equation in time-dependent domains and the problem of debond initiation
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 firstExpand
On the Quasistatic Limit of Dynamic Evolutions for a Peeling Test in Dimension One
Passing to the limit as inertia tends to zero, it is found that the limit evolution satisfies a stability condition; however, the activation rule in Griffith’s (quasistatic) criterion does not hold in general, thus thelimit evolution is not rate-independent. Expand

It is proved that, in contrast to what happens in the undamped case, dynamic solutions converge to the quasistatic one when inertia and viscosity go to zero, except for a possible discontinuity at the initial time. Expand
Existence and uniqueness of dynamic evolutions for a peeling test in dimension one
Abstract In this paper we present a one-dimensional model of a dynamic peeling test for a thin film, where the wave equation is coupled with a Griffith criterion for the propagation of the debondingExpand
Dynamic fracture: an example of convergence towards a discontinuous quasistatic solution
Considering a one-dimensional problem of debonding of a thin film in the context of Griffith’s theory, we show that the dynamical solution converges, when the speed of loading goes down to 0, to aExpand
Existence and convergence results are proved for a regularized model of dynamic brittle fracture based on the Ambrosio–Tortorelli approximation. We show that the sequence of solutions to theExpand

Solvability in noncylindrical domains is studied for some analogs of the first initial-boundary value problem for the wave equation with nonlinear increasing lower-order terms. Considered are theExpand
On the role of kinetic energy during unstable propagation in a heterogeneous peeling test
We study the dynamic debonding of a one-dimensional inextensible film, subject to a monotonic loading and under the hypothesis that the toughness of the glue can take only two values. We firstExpand
