RISStress Dependence of Shear Strength in Fine-Grained Soils and Correlations with Liquid Limit
Publisher: American Society of Civil Engineers
Abstract: The undrained strengths and friction angles of a variety of natural fine-grained soils are investigated over an effective stress range of 0.1 to 10 MPa. The resedimentation technique was used to produce identical saturated ...
Identification of Material Constitutive Laws Representative of Machining Conditions for Two Titanium Alloys: Ti6Al4V and Ti555 3
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Determining a material constitutive law that is representative of the extreme conditions found in the cutting zone during machining operations is a very challenging problem. In this study, dynamic shear tests, which ...
Circumferential Stresses in Pressure Vessel Shells of Revolution

Design Procedure for a Fast and Accurate Parallel Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design procedure for a two degree-of-freedom (DOF) translational parallel manipulator, named IRSBot-2. This design procedure aims at determining the optimal design parameters of the IRSBot-2 such that ...
Sampling Disturbance Effects in Normally Consolidated Clays
Publisher: American Society of Civil Engineers
Abstract: The effects of sampling disturbance are investigated by performing single element triaxial tests in which specimens of normally consolidated resedimented Boston blue clay are disturbed according to the “perfect sampling ...
Where Do We Stand with Fuzzy Project Scheduling?
Publisher: American Society of Civil Engineers
Abstract: Fuzzy project scheduling has interested several researchers in the past two decades; about 20 articles have been written on this issue. Contrary to stochastic project-scheduling approaches that are used by many project ...
Boundaries and Transboundary Water Conflicts
Publisher: American Society of Civil Engineers
Abstract: This paper examines political boundaries to determine if changing the boundary function or placement will lessen conflicts. A political geography approach provides the framework for analysis. Although water managers advocate ...
Experimental Study of Wellbore Instability in Clays
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an extensive program of laboratory model wellbore tests that have been performed to study wellbore instability in saturated clays. The tests were conducted on resedimented Boston blue ...
Compression and Creep of Venice Lagoon Sands
Publisher: American Society of Civil Engineers
Abstract: A laboratory test program was conducted to evaluate the one-dimensional (1D) compression and creep properties of intact sand (and silty-sand) samples from a deep borehole at the Malamocco Inlet to the Venice Lagoon. The ...
Does Calcium Leaching Increase Ductility of Cementitious Materials? Evidence from Direct Tensile Tests
Publisher: American Society of Civil Engineers
Abstract: There is an ongoing debate in the chemomechanics community over whether calcium leaching leads to an increase in brittleness or ductility of cementitious materials. While other research teams have addressed this question ...
