【摘要】 <正> The stress and strain singularities of power hardening material for Mode I fracrure areanalysed according to the fundamental equations of elastic-plastic mechanics. It is foundthat the singularities of all stress and strain components do not change in the thick direction,and neither the six stress components nor the six strain components have the samesingularity.
