A thermodynamically consistent cohesive-frictional interface model for mixed mode delamination

Abstract

We now differentiate between the requirements for new and revised submissions. You may choose to submit your manuscript as a single Word or PDF file to be used in the refereeing process. Only when your paper is at the revision stage, will you be requested to put your paper in to a 'correct format' for acceptance and provide the items required for the publication of your article. To find out more, please visit the Preparation section below. Highlights Highlights are mandatory for this journal as they help increase the discoverability of your article via search engines. They consist of a short collection of bullet points that capture the novel results of your research as well as new methods that were used during the study (if any). Please have a look at the examples here: example Highlights. Highlights should be submitted in a separate editable file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including spaces, per bullet point).

Integration of finite displacement interface element in reference and current configurations

“…5), at ves dierent loading steps: a) u x = 5mm; b) u x = 10mm; c) u x = 15mm; d) u x = 20mm; e) u x = 25mm. Results of numerical simulations with three dierent loading angles γ are compared in Figure 7 with results of small displacement solution and analytical solution, in terms of applied load P vs crack opening displacement d. The good agreement between the dierent solutions can be appreciated, excluding the initial elastic branch for well known motivations induced by elastic beam theory [21].…”

“…Equation (21) shows that the interface elastic parameters cannot be assumed as constant in the deformed conguration but they linearly depend on the ratio between the areas of undeformed surface and deformed surface.…”

“…The evolution of such constitutive model with dierent mode I and mode II fracture energies has been proposed by the same authors in [21]. 4 Interface nite element formulation…”

“…The proposed interface formulation has been implemented in the open source nite element code FEAP [19] with reference to the cohesive-frictional interface model proposed in [20,21]. The results of the numerical simulations for an end-notched double cantilever beam test are proposed and compared with analytical solutions.…”

A general thermodynamical model for adhesive frictional contacts between viscoelastic or poro-viscoelastic bodies at small strains

“…Nevertheless, except [15], friction dissipation was not taken into account in these works. Coupling of cohesive models and friction contact was developed after the pioneering work [62], which assumed the friction is activated after complete cohesive failure, in a series of relevant contributions [2,9,19,22,27,36,37,41,42,53,57,61,64] among others, providing, for isothermal configurations, a continuous transition from the cohesive state to the frictional contact state. However, no rigorous proof of the solution existence or the convergence of a numerical scheme to the exact solution was provided in these works.…”
