“…The shapes and magnitudes of the strain curves obtained using the present procedure are in excellent agreement with those reported by Hammerand and Kapania. It should be noted that the results obtained by Hammerand and Kapania are consistent with the analytical solution 5 . These results are of particular importance because they illustrate that the unloading or recovery behaviour of viscoelastic and orthotropic composites can be realistically simulated using the present procedure.…”

“…Both sets of results show that the tip deflection experienced by the cantilever beam increases with time but the actual rate of increase reduces with time. The results of Hammerand and Kapania are consistent with the analytical solution 5 . Consequently, it can be concluded from the results that the viscoelastic sub-routines contained within ABAQUS is capable of modelling the viscoelastic behaviour of isotropic materials.…”

“…There exists a substantial library of research papers, textbooks and PhD dissertations on the topic. In particular, a number of publications describing the use of finite element techniques to model viscoelastic behaviour have been encountered [2][3][4][5][6][7][8][9] . The majority of them focus on the development of finite element codes to solve specific problems of interest.…”

In this paper a finite element procedure for modelling the viscoelastic behaviour of orthotropic composites is presented. The procedure uses the commercially available finite element package ABAQUS and requires no code development. The procedure utilises two coincident shell elements to model the orthotropic viscoelastic behaviour of a composite laminate. The first element exhibits isotropic and viscoelastic behaviour, while the second element exhibits orthotropic and elastic behaviour. The elements are superimposed in such a way that they are coincident. That is, the two shell elements share the same nodes and hence deform together. Consequently, it is expected that this combined hybrid model will exhibit combined orthotropic and viscoelastic behaviour. Numerical examples are presented to illustrate the capability and accuracy of the new procedure.

“…There is a relatively large number of works reporting on the viscoelastic analysis of polymer composites, see for example Refs [1][2][3][4][5][6][7] . As a result, anisotropic viscoelastic analysis of composite materials is now supported by some commercial fi nite element packages, such as MSC.MARC.…”

This paper deals with the experimental determination of the in-plane mechanical properties of a carbon-epoxy composite laminate in the temperature range of 100 °C to 150 °C. Focus has been on the in-plane shear modulus of the laminate. A time-dependent constitutive model for the in-plane shear modulus has been developed. Material constants for the model were derived from the creep compliance of the laminate, obtained experimentally at various temperatures. The results show that the in-plane shear property of the composite laminate is linear viscoelastic within the temperature range and loading level investigated. The constitutive model was validated experimentally.

Thermo-viscoelastic bending analysis of a shape memory alloy hybrid epoxy beam

The deflection of an epoxy beam with embedded shape memory alloy (SMA) wires subjected to lateral load is predicted based on the thermo-viscoelastic finite-element analysis for the beam. The emphasis has been placed on the effect of thermo-viscoelasticity of the polymeric matrix. The SMA wires, which are located at the neutral surface of the beam, are embedded inside the sleeves and fixed externally at two ends. In this study the classical theory is applied for the beam analysis and Brinson's constitutive relation is used for the SMA. Experiments of SMA hybrid epoxy beam are conducted and the results compare well with the theory.
