Abstract: This Discussion is submitted with the understanding that the authors would respond only to the technical issues with appropriate proofs and not address unrelated items and attack others’ work. ...

Abstract: The disturbed state concept (DSC) and the dissipated energy approach can provide simplified, fundamental, and mechanistic methods for the identification of the initiation and growth of liquefaction in saturated soils under ...

Abstract: A number of models for thermomechanical stress analysis and fatigue failure of materials are reviewed and their capabilities and limitations are identified. The unified disturbed state concept ...

Abstract: The widely used Terzaghi theory for deformation or consolidation in porous materials is based on the effective stress, a rather fictitious quantity, carried by the soil skeleton through the particle contact area, which is ...

Abstract: An understanding of the mechanical behavior of saturated interfaces between structural and geologic materials and joints in rock, subjected to cyclic earthquake-type loading, is important for safe and improved analysis and ...

Abstract: A geosynthetic-reinforced soil retaining wall using full-height concrete wall facing panel was constructed at Tanque Verde Road site for grade-separated interchanges in Tucson, Ariz. Numerical simulation of this wall was ...

Abstract: Realistic predictions of dynamic soil–structure interaction problems require appropriate constitutive models for the characterization of soils and interfaces. This paper presents a unified model based on the disturbed state ...

Abstract: A general constitutive modeling concept called the disturbed state concept (DSC) is developed in this research for the stress-strain and liquefaction behavior of saturated sands. The DSC model is a unified approach and ...
