Mechanical Behaviors of Low-Permeability Sandstone under the Coupled Elastoplastic Damage and Evolved Gas Permeability
Publisher: ASCE
Abstract: Low-permeability sandstone generally exists in oil and gas reservoirs. During oil and gas exploitation, reservoir pressure depletion causes significant plastic deformation and damage evolution. In reservoir history matching, ...
Mechanical Expansion of Thick-Walled Microgroove Tube for High Pressure ACR System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a study on the expansion process, which joins fins to thick-walled microgroove tubes for high pressure air conditioning and refrigeration (ACR) heat exchanger. Experiments of ...
Resistance of Caisson Tip with Internal Bevels for Suction Caissons Penetrating into Clay
Publisher: ASCE
Abstract: Suction caissons with internal bevels at the caisson tip can effectively reduce resistance to make them to penetrate into the seabed easily. This paper describes the failure mechanisms of the soil at the caisson tip with ...
Active Earth Pressure of Narrow Cohesionless Backfill on Inclined Rigid Retaining Walls Rotating about the Bottom
Publisher: ASCE
Abstract: In engineering constructions, the backfill behind retaining walls is usually narrow, and its boundary conditions are asymmetric due to the space limitation. When the retaining wall rotates about the bottom, the direction ...
Error Assessment for Spectral Representation Method in Random Field Simulation
Publisher: American Society of Civil Engineers
Abstract: Random fields, such as the wind velocity field and the seismic ground motion field, are usually simulated by the spectral representation method (SRM). The SRM mainly relies on two methods: the random amplitudes method and ...
