摘要
本文应用弹塑性理论,根据岩石的应力应变关系、峰值强度、残余强度和岩石材料的脆性特性,建立了理想的应变软化模型,并提出了相应的加载准则。文中提出的模型计算方便,所用参数简单,物理意义明确,便于编制有限元程序。
Based on the stress-strain relationship and the properties of peak strength, residual strength, and britleness of rock material, a perfect strain-softening model and related loading criteria are proposed by using the theory of elasto-plasticity. The physical concepts of this model are very clear with simple parameters, which is convenient for numerical analysis including finite element analysis.
