RISHydromechanical Behaviors of Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: In this paper, the hydromechanical behavior of unsaturated soils is explored. A constitutive model is proposed to describe the coupled hydraulic and mechanical behavior of unsaturated soils. The compression stiffness ...
Experimental Investigation and Modeling of the Hydraulic Conductivity of Saturated Bentonite–Claystone Mixture
Publisher: ASCE
Abstract: Mixtures composed of MX80 bentonite and crushed Callovo-Oxfordian (COx) claystone have been considered as one of the promising sealing/backfilling materials in French deep geological disposal for radioactive waste. One of ...
Investigation of Suction Effects Due to Stress Release with Compacted MX80 Bentonite
Publisher: ASCE
Abstract: In this study, the suction induced by stress release was investigated by measuring the suction of instantaneously unloaded MX80 bentonite specimens after wetting in an oedometer either under different vertical stresses or ...
Stress Release–Induced Suction in Unsaturated MX80 Bentonite Pellet and Powder Mixtures
Publisher: American Society of Civil Engineers
Abstract: In this study, a series of suction-control oedometer tests were conducted on unsaturated and saturated MX80 bentonite pellet/powder mixtures. The mixture samples were imposed with various suctions from 0 to 113 MPa ...
On the Evolution of Double Shock Accelerated Elliptic Gas Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The evolution of double elliptic heavygas (SF6) cylinders impacted by a planar shock wave is studied by highspeed camera diagnostics. The minor axes (b) of the elliptic cross sections are aligned perpendicular to the shock ...
Expulsion Intensity Monitoring and Modeling in Resistance Spot Welding Based on Electrode Displacement Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Weld expulsion is one of the most common welding defects during the resistance spot welding (RSW) process, especially for high strength steels (HSS). In order to control and eventually eliminate weld expulsion in production, ...
A Novel Expulsion Control Strategy With Abnormal Condition Adaptability for Resistance Spot Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding expulsion is a common problem in the resistance spot welding (RSW) process, which severely impacts weld quality and surrounding facilities. Existing expulsion control strategies are ineffective for complex and ...
Large-Strain Consolidation of Sludge in Geotextile Tubes Considering Vacuum-Induced Rapid Consolidation and Soil Reconstitution
Publisher: American Society of Civil Engineers
Abstract: Clogging represents a crucial factor severely hindering the vacuum preloading treatment for clayey sludge. However, the underlying mechanism of this occurrence remains insufficiently investigated, limiting the application ...
Large-Strain Consolidation Analysis for Clayey Sludge Improved by Horizontal Drains
Publisher: ASCE
Abstract: The use of prefabricated horizontal drains (PHDs) with combined surcharge and vacuum preloading is an effective improvement approach for dredged clayey slurries. However, there is no large-strain analysis method for ...
Tensile Strength of Fiber-Reinforced Soil
Publisher: American Society of Civil Engineers
Abstract: The tensile strength of soil is an important mechanical parameter that controls the development of tension cracks. In this study, randomly distributed polypropylene fibers were employed to improve soil tensile behavior. ...
