Double peeling of elastic pre-tensioned tapes
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 30
Abstract
Peeling is a physical mechanics involved in the detachment of many natural and industrial applications. In this paper, we investigate the double peeling of an endless elastic pre-stressed tape adhering to a flat smooth rigid substrate. Solutions are given in closed form and their stability is discussed. Critical pull-off force needed to detachment is shown to be higher for pre-stressed tapes. However, when a pre-stress is high, tapes behave differently and may spontaneously detach from the rigid substrate.

Thermal degradation in Carrara marbles as the cause of deformation of cladding slabs
Marble slabs, typically used as façade panels to externally cover buildings, might permanently deform after a certain time of environmental exposure. This phenomenon, called bowing, is generally accompanied by a...
Strain gradient elasticity within the symmetric BEM formulation
The symmetric Galerkin Boundary Element Method is used to address a class of strain gradientelastic materials featured by a free energy function of the (classical) strain and of its (first) gradient. With respectto...
Effect of inhomogeneous distribution of non-metallic inclusions on crack path deflection in G42CrMo4 steel at different loading rates
An inhomogeneous distribution of non-metallic inclusions can result from the steel casting process. The aim of the present study was to investigate the damaging effect of an inhomogeneous distribution of nonmetall...
Effect of segregations on mechanical properties and crack propagation in spring steel
Considerable efforts have been made over the last decades to improve performance of spring steels, which would increase the service time of springs and also allow vehicles weight reduction. There are differen...
Effective properties of a new auxetic triangular lattice:an analytical approach
In this article we propose a new auxetic periodic lattice with negative Poisson's ratio which tends tothe limit ν=-1 under particular conditions. We have studied its generation and kinematic, and we give a fulldesc...
