A prestressing procedure is proposed for reduction of stress concentrations at the leading edges of adhesive bondlines in composite skin/ ange assemblies. A Ž niteelementanalysisof a speciŽ c geometryof such an assembly is presented,whichaccounts for nonlinear viscoelastic deformation of the adhesive. Design diagrams based on elastic analysis are constructed for evaluation of prestress forces ...

Is the maximum force required to detach a rigid sphere from viscoelastic substrate dependent on initial value of contact radius? Experimental and theoretical investigations reported in literature have given opposite responses. Here, we try answer above question by exploiting fully deterministic model which adhesive interactions are described Lennard-Jones potential behaviour with standard linea...

A majority of antibiotic-resistant bacterial infections in the United States are associated with biofilms. Nanoscale biophysical measures are increasingly revealing that adhesive and viscoelastic properties of bacteria play essential roles across multiple stages of biofilm development. Atomic Force Microscopy (AFM) applied to strains with variation in antimicrobial resistance enables new opport...

Pressure sensitive mounting tapes provide a quick and effective fastening method compared to most mechanical joining techniques. Due to the viscoelastic nature of pressure sensitive adhesives their response to mechanical and climatic stress in terms of durability is different from most structural adhesives. While the feature of compensating differences in thermal expansion of bonded members and...

Abstract When quickly detaching an elastomer from a counterface, viscoelasticity dramatically increases the perceived adhesion relative to its adiabatic or equilibrium value. Here, we report simulations on sticking contact between rigid cylinder and viscoelastic half space revealing maximum in work of separation at intermediate pull-off velocities. Maximum tensile forces yet increase monotonica...

A backwards-tracking Lagrangian–Eulerian method is used to simulate planar viscoelastic squeeze flow. The momentum and continuity equations are discretized with the finite volume implicit immersed boundary conditions describe objects in domain. flow, which involves moving solid geometry as well free surface chosen for its relevance industrial applications, such adhesive parts assembly hemming. ...
