Fundamental issues on the constitutive modeling of geomaterials and on the application to numerical analyses are briefly discussed in this paper. Following the discussion on the role of the constitutive model in the numerical analysis, good constitutive model, strongly depending on the objective of the analysis, are discussed with some examples. Fundamental requirements of the constitutive model are briefly reviewed and some examples violating the requirements are indicated with an emphasis on the pressure dependent elastic shear modulus. Recent developments in the constitutive modeling of geomaterials are summarized and the problems requiring further developments of constitutive models are indicated. The application of the nonlinear constitutive model and numerical analysis to the design of geo-structures is still a challenging problem and is far from the ordinary useful method.
