Debonding of FRP and thin films from an elastic half-plane using a coupled FE-BIE model

The effect of material anisotropy on the mechanics of a thin-film/substrate system under mechanical and thermal loads

“…Moreover, a thin-film structure may experience excessive thermal gradients as it converts the heat to electric power in thermogenerator elements [13]. In the case of mechanical loading, thin films offer sound prevention as well as wear and damage resistance which can be used as stiffeners or cover plates in the engineering structures [14–16]. Therefore, it is important to analyze the stress state in the thin-film/substrate system by considering the material anisotropy under both the thermal and the mechanical loadings.…”

Buckling of beams and coatings of finite width in bilateral frictionless contact with an elastic half-space

“…The FE-BIE coupling method has been originally introduced for the static analysis of both Euler-Bernoulli and Timoshenko beams in frictionless contact with a two-dimensional half-space (Tullini and Tralli, 2010) and it has been already extended to the corresponding buckling problem (Tullini et al, 2013a, Tullini et al, 2013b, Baraldi, 2019, and to the case of a fully adhesive contact (Tullini et al, 2012;Tezzon et al 2015;Tezzon et al 2016;Tezzon et al 2018). Effects of sharp and smooth beam edges in the buckling of a Timoshenko beam in frictionless and bilateral contact with an elastic half-plane was analysed in Falope et al (2020).…”

Static stiffness of rigid foundation resting on elastic half-space using a Galerkin boundary element method

“…The proposed numerical approach has been recently used to study the in-plane bending of Timoshenko beams in bilateral frictionless contact with an elastic isotropic half-space making use of a Finite Element-Boundary Integral Equation (FE-BIE) method [33], allowing to obtain fast and accurate results in terms of beam displacements and contact tractions. The FE-BIE method was extensively used with elastic two-dimensional substrate, e.g., in the static analysis of Timoshenko beams and frames in frictionless [34,35] or fully adhesive [36,37] contact with an half-plane, and also to study bars and thin coatings [38,39]. Moreover, the FE-BIE coupling method was also used to analyze the buckling of Euler-Bernoulli [40,41] and Timoshenko [42] beams in bilateral frictionless contact with an elastic half-plane.…”
