Mix-Mode Elastic Finite Element Formulation for Bonded Granular Material Considering Rotation of Particles
Publisher: American Society of Civil Engineers
Abstract: Rotation of particles in granular material is an important mechanism, which is responsible for the distinct feature of moment transfer within granular material. A couple-stress continuum is adopted to model such effect. ...
Anisotropic Nonlinear Elastic Model for Particulate Materials
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development of an elastic model for particulate materials based on micromechanics considerations. A particulate material is considered as an assembly of particles. The stress–strain relationship for ...
Model for Granular Materials with Surface Energy Forces
Publisher: American Society of Civil Engineers
Abstract: In light of environmental differences (such as gravitational fields, surface temperatures, atmospheric pressures, etc.), the mechanical behavior of the subsurface soil on the Moon is expected to be different from that on ...
Heterogeneous Strain and Bonded Granular Structure Change in Triaxial Specimen Studied by Computer Tomography
Publisher: American Society of Civil Engineers
Abstract: In recent years, the method of x-ray computer tomography imaging has been used to characterize the microstructure of asphalt concrete, cement concrete, soil, and rock. This paper focuses on developing an algorithm that ...
Evaluation of Two Homogenization Techniques for Modeling the Elastic Behavior of Granular Materials
Publisher: American Society of Civil Engineers
Abstract: This paper discusses the capabilities of two homogenization techniques to accurately represent the elastic behavior of granular materials considered as assemblies of randomly distributed particles. The stress-strain ...
Elastic Model for Partially Saturated Granular Materials
Publisher: American Society of Civil Engineers
Abstract: This paper presents the development of an elastic model for partially saturated granular materials based on micromechanical factor consideration. A granular material is considered as an assembly of particles. The stress-strain ...
Micromechanical Analysis for Interparticle and Assembly Instability of Sand
Publisher: American Society of Civil Engineers
Abstract: Instability of granular material may lead to catastrophic events such as the gross collapse of earth structures, and thus it is an important topic in geotechnical engineering. In this paper, we adopt the micromechanics ...
Elastoplastic Model for Clay with Microstructural Consideration
Publisher: American Society of Civil Engineers
Abstract: Clay material can be considered as a collection of clusters, which interact with each other mainly through mechanical forces. From this point of view, clay is modeled by analogy to granular material in this paper. An ...
