based on the constitutive framework of unsaturated soils established by the continuum porous medium soil mechanics, an elastoplastic model for unsaturated soils in triaxial stress state is formulated.
基于连续介质土力学的本构模型框架,提出了一个三轴应力状态下的非饱和土本构模型。
based on the concept of strain energy density, the triaxial stress state and constraint of the elements of the crack near by tip are discussed by using the nondimensional parameter r .
