MULTI-SCALE FE COMPUTATION FOR THE STRUCTURES OF COMPOSITE MATERIALS WITH SMALL PERIODIC CONFIGURATION UNDER CONDITION OF COUPLED THERMOELASTICITY

In this paper,the multi-scale computational method for a structure of compositematerials with a small periodic configuration under the coupled thermoelasticity condition is presented.The two-scale asymptotic(TSA)expression of the displacement and the increment of temperature forcomposite materials with a small periodic configuration under the condition of thermoelasticity arebriefly shown at first,then the multi-scale finite element algorithms based on TSA are discussed.Finallythe numerical results evaluated by the multi-scale computational method are shown.It demonstratesthat the basic configuration and the increment of temperature strongly influence the local strains andlocal stresses inside a basic cell.
