RISEnhanced Voids Growth Model for Ductile Fracture Prediction of High-Strength Steel Q690D under Monotonic Tension: Experiments and Numerical Simulation
Publisher: ASCE
Abstract: Accurate prediction of progressive damage and failure of structural steels is a nontrivial issue in practical design and assessment of steel structural buildings. It appears far more important in the fracture-oriented ...
Application of Discrete-Element Numerical Simulation for Calculating the Stability of Dangerous Rock Mass: A Case Study
Publisher: ASCE
Abstract: An unstable rock mass is a common geological hazard in water conservancy and hydropower engineering in southwest China. The mechanical properties of a rock mass joint and the internal and external physical environment are ...
Numerical Model of a Tandem Reciprocating Hydraulic Rod Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical model of a tandem reciprocating hydraulic rod seal, consisting of two elastomeric U cup seals, has been constructed. It is applicable to cases in which the stroke length is ...
Soft EHL Simulations of U-Cup and Step Hydraulic Rod Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical soft elastohydrodynamic lubrication model of a reciprocating hydraulic seal has been used to simulate the performance of a U-cup seal and a step seal in a conventional actuator. ...
Behavior of Composite Beam-Column Joints in a Middle-Column-Removal Scenario: Experimental Tests
Publisher: American Society of Civil Engineers
Abstract: A series of experiments has been conducted to investigate the failure modes and ductility of composite beam-column joints in a middle-column-removal scenario. Composite web cleat and flush end plate connections were studied. ...
Numerical Model of a Reciprocating Hydraulic Rod Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical model of an elastomeric reciprocating hydraulic rod seal has been constructed. The model consists of coupled fluid mechanics, deformation mechanics, and contact mechanics analyses, ...
Biased Information Passing Between Subsystems Over Time in Complex System Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the early stage design of largescale engineering systems, design teams are challenged to balance a complex set of considerations. The established structured approaches for optimizing complex system designs offer ...
Component-Based Modeling for Steel and Composite Beam-Column Joints Subjected to Quasi-Static and Impact Loads under Column Removal Scenarios
Publisher: ASCE
Abstract: This paper describes a component-based modeling approach for bare steel and composite beam-column joints subjected to quasi-static and impact loads under column removal scenarios. Two types of beam-column joints, viz. fin ...
Experimental Study on Progressive Collapse of 3D Steel Frames under Concentrated and Uniformly Distributed Loading Conditions
Publisher: ASCE
Abstract: Structures are expected to be robust enough to avoid widespread local failure caused by extreme loading events, so that the complete or disproportional collapse of buildings can be averted. In the last decades, numerous ...
Flexural Behavior and Rotation Capacity of Welded I-Beams Made from 690-MPa High-Strength Steel
Publisher: ASCE
Abstract: In this study, the flexural behavior and rotation capacity of welded I-beams made from 690-MPa high-strength steel were investigated through experimental tests and numerical simulations. In the experimental program, a total ...
