On Cvitical Darnage of Cement Concrete LiGuoqiang,Deng Xuejun 1995, 14(3): 21-26.  Abstract ( )   PDF (341KB) ( )   The conditions and featwres of critical damage are firstly investigated for cement concrete in this paper.Futher,the renormalixation group model and stationary point equation are established. With the aid of normal treatment of damage,the area density of critical damage is obtained,which coincides with exporienccd values. The results have practicaI mean-ing to damage mechan ics an alyses of cement concrete and other brittle materials. References | Related Articles | Metrics
