RISA Simple Numerical Method for Contact Analysis of Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a simple method that may be used to calculate the pressures and surface displacements in contacts of rough surfaces. A main feature of the method is that the pressure is ...
Closure to “Experimental and DEM Examinations of K0 in Sand under Different Loading Conditions” by Y. Gao and Y. H. Wang
Publisher: American Society of Civil Engineers
Robust Testing Procedure for Detection of Multiple Blunders
Publisher: American Society of Civil Engineers
Abstract: Blunder detection is a topic of great interest to surveyors and mappers because undetected blunders significantly distort the solution. Therefore, a robust testing procedure has been developed for the detection and ...
Stress–Strain Relationship for Metal Hollow Sphere Materials as a Function of Their Relative Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress–strain relationship for uniaxial compression of a metal hollow sphere material in large strains is obtained using a simplified model for the spheres’ deformation within a 3D block ...
Effect of Temperature Variation on the Full-Range Behavior of FRP-to-Concrete Bonded Joints
Publisher: American Society of Civil Engineers
Abstract: Service temperature variations (thermal loadings) may significantly affect the behavior of the bond between externally bonded fiber reinforced polymer (FRP) and concrete. This paper presents an analytical solution for the ...
Bond-Slip Model for FRP Laminates Externally Bonded to Concrete at Elevated Temperature
Publisher: American Society of Civil Engineers
Abstract: This paper presents a nonlinear local bond-slip model for fiber reinforced polymer (FRP) laminates externally bonded to concrete at elevated temperature for future use in the theoretical modeling of fire resistance of ...
Simple Method for Predicting Temperatures in Insulated, FRP-Strengthened RC Members Exposed to a Standard Fire
Publisher: American Society of Civil Engineers
Abstract: Fire safety is a significant concern for fiber-reinforced-polymer (FRP)–strengthened RC structures, particularly for indoor applications. To satisfy fire resistance requirements, fire insulation layers may be provided to ...
Mechanical Behavior of Metallic Hollow Sphere Materials: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: Different from conventional metal foams, sintered metallic hollow sphere (MHS) material contains a certain volume fraction of enclosed pore space inside the spheres, as well as the interstitial porosity between the sintered ...
Experimental Verification of the Flexibility-Based Damage Locating Vector Method
Publisher: American Society of Civil Engineers
Abstract: In recent years, numerous approaches have been proposed for detecting damage in structures, in which the flexibility-based damage locating vector (DLV) method is one of the promising techniques. By computing a set of load ...
Experimental Characterizations of Contact Movement in Two-Dimensional Rod Assembly Subjected to Direct Shearing
Publisher: American Society of Civil Engineers
Abstract: This study explored the features of particle motion and, in particular, the associated movements at contacts in response to direct shearing. A tailor-made direct shear box equipped with an image system was set up. The ...
