摘要:
Stress distribution in a perfectly plastic disk caused by a circular heat source of constant output is investigated. It is shown that, dependent on the ratio of the radius of the disk to the radius of the heat source, Tresca's yield condition assumes different forms. In certain cases, the plastic zone is composed of two parts associated with different branches of the yield condition. The critical time for avoiding secondary plastic flow is discussed.
