FINITE ELEMENT FORMULATION OF GENERAL ELECTROTHERMOELASTICITY PROBLEMS

This paper is concerned with the devclopmcnt of consistent discrctc models. via thc concept of tinite elements. of linear and non-linear electrothcrmomechanical behaviour of continuous bodies. In the development. general energy balances are utilizcd to derive equations govcrning electromagnetic fields over an element and coupled equations of motion and heat conduction of a typical clcmcnt of the continuum. These cquations make it possiblc to study a general class of field problcms involving arbitrary geometries and boundary condit ions. Sample problems arc includcd
