摘要
通过粗粒料三轴剪力试验和强度试验资料 ,进行回归得到了粗粒料的强度准则τ =Aσb,并以此为屈服准则 ,结合弹塑性理论建立了粗粒料的弹塑性本构模型 ,该模型连续、不存在奇点 ,模型参数少。推导出粗粒料的弹塑性矩阵Dep,试验结果与模型计算结果吻合较好。
Through regressing the strength curves of coarse materials in test,establishing a strength criterion ( τ=Aσ b ), based on this yield criterion and elastic plastic theory,establishing a elastic plastic constitutive relation model of coarse material,which is continuative,no odd and has less parameter,and giving the elastic plastic matrix D ep .The reasonableness and feasibility of this model are proven by practice.
