Discussion of “<i>Generalized Creep and Stress Relaxation Model for Clays</i>” by R. I. Borja (November, 1992, Vol. 118, No. 11)
Publisher: American Society of Civil Engineers
Additional Insight into Generalized Bounding Surface Model for Saturated Cohesive Soils
Publisher: ASCE
Abstract: The generalized bounding surface model (GBSM) is a fully three-dimensional, time-dependent model for saturated cohesive soils that accounts for both inherent and stress-induced anisotropy, as well as strain softening and ...
An Associative and Non-Associative Anisotropic Bounding Surface Model for Clay
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An anisotropic elastoplastic bounding surface model with non-associative flow rule is developed for simulating the mechanical behavior of different types of clays. The non-associative flow rule ...
Application of an Enhanced Anisotropic Bounding Surface Model in Simulating Deep Excavations in Clays
Publisher: American Society of Civil Engineers
Variable Bulk Modulus Constitutive Model for Sand
Publisher: American Society of Civil Engineers
Abstract: A quasi-linear elastic constitutive model is proposed to describe the behavior of sand well below failure. It is based on isotropic compression tests and captures the increase in stiffness due to confinement—a unique ...
Modeling the Behavior of Geosynthetic Encased Columns: Influence of Granular Soil Constitutive Model
Publisher: American Society of Civil Engineers
Abstract: Using a high-strength geosynthetic for encasement of granular columns increases the strength of a given column and improves its stress-displacement response. This paper describes the results from a series of three-dimensional ...
Analyzing Dynamic Behavior of Geosynthetic-Reinforced Soil Retaining Walls
Publisher: American Society of Civil Engineers
Abstract: An advanced generalized plasticity soil model and bounding surface geosynthetic model, in conjunction with a dynamic finite element procedure, are used to analyze the behavior of geosynthetic-reinforced soil retaining ...
Constitutive Modeling of Geomaterials
Publisher: American Society of Civil Engineers
Laboratory Assessment of the Mechanical Properties of an Unsaturated Mid-Atlantic Silty Sand
Publisher: ASCE
Abstract: Natural soil formation processes involve variable particle size distributions that vary spatially within a deposit, giving rise to an array of soils that transition from one general soil type to another within essentially ...
Foundation‐Response Predictions Below Caisson‐Retained Island
Publisher: American Society of Civil Engineers
Abstract: The results of two‐dimensional (axisymmetric) finite element analyses of a clay sea bed located in the Canadian Beaufort Sea are described herein. The sea bed is subjected to loads associated with excavation, construction ...
