  • An implicit finite difference formulation for treating multiphase flow in wet porous soils 

    Hassig, Paul J. (Structures Laboratory (U.S.), 1988-04)
    Abstract: A one-dimensional (1-D) implicit multiphase finite difference formulation which calculates the relative flow and dynamic stress behavior in wet porous soils has been developed and incorporated into a computer ...
  • An endochronic plasticity model for ISST soils 

    Valanis, K. C.; Read, H. E. (Harold Edwin) (Structures Laboratory (U.S.), 1988-05)
    Abstract: A new endochronic plasticity model that has the capability to describe both densification and dilatancy is described and applied to laboratory data from reconstructed ISST soils generated by the US Army Engineer ...
  • Simplified analysis of concrete gravity dams including foundation flexibility 

    Nau, James M. (Structures Laboratory (U.S.), 1989-09)
    Abstract: The objective of this study was to develop a model for the flexible foundation rock beneath a dam and to incorporate this model into the finite element procedure and a two-dimensional model of the monolith, SDFDAM. ...
  • Plane wave propagation in random granular media 

    Ostoja-Starzewski, Martin. (Structures Laboratory (U.S.), 1992-02)
    Abstract: We show that a Markov property of disturbance propagation forms the basis for a study of wavefronts in graph representable microstructures. Stochastic Huygens' minor principle is developed to analyze wavefront ...
  • Constitutive modeling of rocks with internal cracks 

    Krajcinovic, Dusan.; Basista, Michal (Structures Laboratory (U.S.), 1992-04)
    Abstract: The analytical model discussed and formulated in this report focuses on the derivation of a constitutive model for low-porosity, crystalline rocks subjected to compressive stresses. The proposed model is inspired ...
  • Stochastic models of wavefront propagation in random granular media 

    Ostoja-Starzewski, Martin. (Structures Laboratory (U.S.), 1992-08)
    Abstract: Determination of the effects of material microscale randomness on wavefront propagation is the focus of this report. The study is set in the context of one-dimensional microstructures with material randomness, ...
  • Constitutive modeling of rocks with internal cracks and pores 

    Krajcinovic, Dusan.; Lubarda, Vlado A. (Structures Laboratory (U.S.), 1994-02)
    Abstract: The report considers fundamental issues of the constitutive modeling of rocks with internal cracks and pores. Phenomenological and micromechanically inspired damage models for brittle deformation of rocks are ...
