The steady-state thermally induced local effects in laminated composite materials are investigated from the micro- and macromechanical points of view. The micro-mechanical model is represented by the alternating layers of a perfectly bonded matrix-reinforcement system while the macromechanical counterpart is characterized by the effective thermal and mechanical properties of the constituent layers. The solutions are obtained within the framework of linear plane thermoelasticity via the Fourier transform technique and the flexibility/stiffness matrix method. As a numerical illustration, the micro- and macromechanical temperature and thermal stress fields due to given surface temperature distributions are presented to measure the degree of correspondence between the two models. Considerable discrepancies are observed to exist between the micro- and macromechanical thermal stress fields, especially, in regions involving high temperature gradients. |
