THE STRESS FIELD IN A CURRENT-CARRYING PLATE WITH A SIDE-CRACK UNDER THE ACTION OF MECHANICAL LOADING

By means of coordinate transformation, the part of stressesin the expression of stress field caused by temperature at the moment ofapplication of transient current on the platewith a side-crack was separated and expressed in polar coordinate. The stress field near the penetrate crack tip of type I was obtained.Through adding the stress field caused by temperature to the stress causedby tension loaded in the distance, the stress field in the current-carryingplate with a side-crack under the action of mechanical loading could beobtained in polar coordinate. An example is provided.
