“…This theory is known as refined first order shear deformation theory (RFSDT). A further improvement in this direction is due to Di Sciuva [35], Bhaskar et al [2], Cho et al [8,16] and some other investigators. They included the condition of zero transverse shear stress at top and bottom of the plate in addition to the shear stress free conditions at the layer interfaces.…”

Buckling analysis of laminated composite plates is carried out by using an efficient C 0 FE model developed based on higher order zigzag theory. In this model the first derivatives of transverse displacement have been treated as independent variables to overcome the problem of C 1 continuity associated with the FE implementation of the plate theory. The C 0 continuity of the present FE model is compensated in the stiffness matrix calculations by using penalty parameter approach. Numerical results and comparison with other existing solutions show that the present model is very efficient in predicting the buckling responses of laminated composites.

“…The mathematical involvement in these plate theories is quite heavy and the solution becomes quite expensive in a multilayered plate, as the unknowns are dependent on number of layers. There is another class of layer wise plate theories [1,6,7,9,14,15,22] where the unknowns of different planes are expressed in terms of those of a particular plane using the condition of shear stress continuity at the layer interfaces. The number of unknowns is reduced in these plate theories considerably [1,6,7,9,14,15,22] .…”

“…The unknowns at the different interfaces are subsequently expressed in terms of those at the reference plane through satisfaction of transverse shear stress continuity at the layer interfaces. A further improvement in this direction is due to Di Sciuva [15], Bhaskar et al [1], Cho et al [6,7] and some other investigators who considered the variation of in-plane displacements to be a superposition of a piecewise linearly varying field on an overall higher order variation. Carrera [2] and Demasi [11] considered higher order terms in the displacement field, using Mukarmi's [21] zig-zag function and assumptions for transverse stresses brings about a large number of solution variables.…”

A C0 continuous finite element model is developed to model the refined higher order shear deformation theory. The proposed element is an upgraded version of an element based on higher order shear deformation theory. The C 0 continuity of the present element is compensated in the stiffness matrix calculations. The computational efficiency is achieved by the C 0 continuous finite element model by satisfying the inter-laminar shear stress continuity at the interfaces and zero transverse shear stress conditions at plate top and bottom. The performance of the upgraded element is illustrated with many numerical examples.

“…In literature many models are known for multi-layered beams and plates [29,[39][40][41][42][43][44] but no attempts can be found with respect to modelling the interface dissipative actions. In this section, a multi-layered beam model based on zig-zag beam and plates theory addressing this issue is presented.…”

Abstract:In this work, the dissipative properties of different coating solutions are compared and a beam mechanical model, taking into account of dissipative actions at the interface between different layers is proposed. The aim is to find optimal coatings to be employed in the production of composites with high damping properties. The investigated coating layers are obtained from different materials and production processes, and are applied on different metallic substrates. The composite specimens, in the form of slender beams, are tested by means of forced excitation dynamic measurements. Force and displacement experimental data, in a wide range of excitation frequencies, are used to estimate the system damping properties. Homogeneous, uncoated specimens are also tested for comparison. A specific identification procedure is used to identify the specimens stress-strain relationship in the frequency domain. The ratio of the imaginary part and the modulus of the specimen estimated complex frequency response function is considered as a measurement of the damping behaviour. A modified third order multi layered beam model, based on the zig-zag beam theory, is proposed. The model takes into account the contribution to the damping behaviour of the frictional actions and slipping at the interface between layers. Frictional actions are modelled by means of a complex, elasto-hysteretic contribution.
