RISAnalytical Solution of a Borehole Problem Using Strain Gradient Plasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical solution is presented for the borehole problem of an elasto-plastic plane strain body containing a traction-free circular hole and subjected to uniform far field stress. A strain ...
The Coupling of the Annual Cycle and ENSO Over the Tropical Pacific
Publisher: American Meteorological Society
Abstract: In the tropical Pacific, the annual variation of sea surface temperature (SST) consists of two distinct components with respect to the equator, 1) an antisymmetric extratropical annual cycle and 2) a symmetric equatorial ...
Critical Velocities of Single-Layer and Two-Layer Composite Tubes of Transversely Isotropic Materials Based on a Potential Function Method in Three-Dimensional Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Critical velocities of a single-layer tube of a transversely isotropic material and a two-layer composite tube consisting of two perfectly bonded cylindrical layers of dissimilar transversely isotropic materials are ...
Axisymmetric Failure Mechanism of a Deep Cavity in Layered Soils Subjected to Pore Pressure
Publisher: American Society of Civil Engineers
Abstract: To investigate the roof stability of deep cavities in layered soils, an axisymmetric failure mechanism based on the existing mechanism is proposed. Because deep cavities are generally under the water table, the adverse ...
Modified Skew Bending Model for Segmental Bridge with Unbonded Tendons
Publisher: American Society of Civil Engineers
Abstract: Segmental bridges with unbonded prestressed tendons have some advantages over conventional concrete bridges, such as weather-independent construction and the corrosion protection of the prestressing tendons. This paper ...
Unified Approach for Analysis of Box-Section Members under Combined Actions
Publisher: American Society of Civil Engineers
Abstract: Reinforced concrete (RC) structural elements with box sections are commonly used in the horizontal and vertical structures of bridges. Reinforced concrete structures in bridges have often failed under the combined forces ...
Limit Analysis of Anchor Trapdoor Embedded in Nonhomogeneous and Nonlinear Soils
Publisher: American Society of Civil Engineers
Abstract: The anchor trapdoor provides a simple and economical system widely used to study the stability of similar geotechnical engineering structures, such as foundations and tunnels. In this study, the passive and active failure ...
Seismic Active Earth Pressure for Soils with Tension Cracks
Publisher: American Society of Civil Engineers
Abstract: It is widely acknowledged that the occurrence of seismic force and cracks will increase the active earth pressure acting on a retaining wall. In this work, a kinematic approach for the evaluation of seismic active earth ...
Stability of Tunnel Roof in Nonhomogeneous Soils
Publisher: American Society of Civil Engineers
Abstract: The stability of tunnel roof is investigated in nonhomogeneous soils using the theory of plasticity. Based on the nonlinear failure criterion, the expressions of tunnel roof in nonhomogeneous soils are deduced, and the ...
Seismic Active Earth Pressure for Soils with Tension Cracks
Publisher: American Society of Civil Engineers
Abstract: It is widely acknowledged that the occurrence of seismic force and cracks will increase the active earth pressure acting on a retaining wall. In this work, a kinematic approach for the evaluation of seismic active earth ...
