A viscoelastic and geometrically nonlinear finite element analysis is performed to investigate the stress relaxation and deflection of a laminated cylindrical shell under thermal loading. Incremental viscoelastic constitutive equations are derived to predict the stress relaxation. The finite element program is developed using a 3-D degenerated shell element, the first order shear deformation theory and the updated Lagrangian formulation, The viscoelastic and geometrically nonlinear analysis is executed for laminated shells with cross-ply and angle-ply stacking sequences, and its results are compared with those obtained from geometrically linear and viscoelastic analyses. The numerical results show that viscoelasticity and geometrical nonlinearity affect on the deflections and stresses of laminated cylindrical shells.

The paper presents 3-D viscoplastic analysis of adhesively bonded single lap joint considering material and geometric nonlinearity. Total Lagrangian formulation is used to develop a 3-D finite element for geometric nonlinear analysis. The overall geometry of the single lap joint, the loading, and the boundary conditions has been considered, both according to the ASTM testing standards and from those adopted in earlier investigations. The constitutive relations for the adhesive are developed using a pressure-dependant (modified) von Mises yield function and Ramberg-Osgood idealisation for the experimental stress-strain curve. The adherends and adhesive layers are both modelled using 20-noded solid elements. However, observations have been made, in particular, on peel and shear stresses in the adhesive layer, which provide useful insight into the 3-D nature of the problem.

“…Kinloch and Kodokian [2] used the three-point bending specimen to study the fracture energy, while Sato [3] studied the absorbed energy in a CFRPaluminium alloy beam. Roy and Reddy [4] investigated the dependence of the resonance frequencies and loss factor on the adhesive shear modulus, lap ratio and strap thicknesses. Lawrence Wu et al [5] measured the absorption energy in electronic adhesive joints using the Hopkinson bar technique.…”

This work consists of investigating the dynamic shear behaviour of adhesively bonded assemblies at high rates of loading. A double lap joint sample was adopted, such as the compressive wave, and transformed to a shear loading within the adhesive layer. The tool used for this target is the Split Hopkinson Pressure Bar (SHPB). A temperature of 20°C and hygrometry of 50% are the ambiance conditions used in the sample in order to avoid temperature and humidity effects. The adhesive material is the cyanoacrylate, while the adherent material is steel. The influence of high rates is remarkable on these bonded assemblies.
