RISStructural Performance of Cold-Formed Steel Unstiffened and Edge-Stiffened Channel Section Beams
Publisher: American Society of Civil Engineers
Abstract: An experimental program and numerical study on the structural performance of cold-formed steel unstiffened and edge-stiffened channel section members under major axis bending are presented in this paper. Channel sections ...
Studies in Direct Tooling Using Stereolithography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rapid prototyping (RP) technologies are valuable for reducing product development cycle times by creating physical models for visual inspection and form-fit studies directly from a 3-D database. ...
Beam-Column Tests of Cold-Formed Steel Built-Up Closed Sections
Publisher: ASCE
Abstract: This study aimed to investigate the buckling behavior of cold-formed steel built-up closed section members subjected to combined minor axis bending and compression. The channels were fabricated from zinc-coated steel sheets ...
Thermal Phase Transformation and Residual Stress Estimation of Multi-Layer Materials for Cylindrical or Flat Shape
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The estimation of the thermal, phase transformation, and residual stresses in multilayer materials during arbitrary loading is a complex problem, which is important in many manufacturing processes. ...
Thermomechanical Analytical 3D Thermal/Stress Estimation Sidewall Grinding Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general three-dimensional thermal/stress grinding model, based on thermal and elastic/plastic classical analytical solutions, has been developed in this paper. The thermal model can predict the ...
Characteristics of a Debris-Flow Drainage Channel with a Step-Pool Configuration
Publisher: American Society of Civil Engineers
Abstract: Theoretical analysis and experimental testing of a debris-flow drainage channel with a step-pool configuration are conducted in this paper. The design conditions of the drainage channel with step-pool configuration were ...
Rapid Perception of Public Opinion in Emergency Events through Social Media
Publisher: ASCE
Abstract: Due to its near-real-time crowdsourcing nature, social media demonstrates a great potential of rapidly reflecting public opinion during emergency events. However, systematic approaches are still desired to perceive public ...
Mechanical Properties of QH-E Lunar Soil Simulant at Low Confining Stresses
Publisher: American Society of Civil Engineers
Abstract: The low-moon gravity has a significant influence on the mechanical properties of lunar soils at low-stress levels. To better understand the shear strength and deformation behavior of lunar soils at low confining stress and ...
Numerical Simulation of Turbidity Current in Approach Channels with a Closed End
Publisher: ASCE
Abstract: This study aims to gain insights into turbidity currents in approach channels with a closed end. A vertical two-dimensional numerical model was introduced, which considers the viscosity of sediment and assumes rheological ...
