RISMultilayer Modeling of Delaminated Bilayer Beams and Its Application to Fracture and Buckling Analysis
Publisher: ASCE
Abstract: A new beam element only having the translational displacement degrees of freedom is developed to analyze fracture and buckling behaviors of bilayer beams or columns with delamination using the multilayer modeling method. ...
Using Steady Flow Force for Unstable Valve Design: Modeling and Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In single stage electrohydraulic valves, solenoid actuators are usually used to stroke the main spools directly. They are cheaper and more reliable than multistage valves. Their use, however, ...
New Rock Bolt Model and Numerical Implementation in Numerical Manifold Method
Publisher: American Society of Civil Engineers
Abstract: A beam-element-based rock bolt model is proposed in this paper. The proposed model can not only simulate the compression and tension deformations of bolts in the rock block but also capture the interaction between the bolt ...

Novel Element for Fracture Analysis of Delaminated Layered Composite Plates Using the Multilayer Modeling Method
Publisher: American Society of Civil Engineers
Abstract: AbstractA novel element is proposed for fracture analysis of layered composite plates with
delamination using the multilayer modeling method. The upper and lower subplates are
both divided into one or multiple sublayers, ...
Three-Dimensional Multi-Morphology TPMS-Based Microchannel Design Method for Conformal Cooling in Injection Molding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Triply periodic minimal surface (TPMS) possesses diverse morphological characteristics, such as pore sizes, porosity, and structural types. Integrating TPMS-based microchannels into micro-cellular cooling structures is ...
The Impact Responses of a Pervious Concrete Wall with a Sand Cushion against Rockfall: A Full-Scale Experimental Study
Publisher: American Society of Civil Engineers
Abstract: The Zhala hydropower station plant was under the threat of rockfalls induced from a high slope, especially in rainy seasons. This paper proposes an innovative protection structure consisting of a pervious concrete wall and ...
An Elastoplastic Linear Strengthening Model to Estimate the Impact Force Generated by Rockfall on Sand Cushion
Publisher: American Society of Civil Engineers
Abstract: Sand cushions for passive protection structures could reduce the damage that is induced by rockfall impact. Therefore, evaluation of the peak impact force generated by rockfall on the sand cushion is significant to the ...
Numerical Analysis of Unsaturated Seepage Flow in Two-Dimensional Fracture Networks
Publisher: American Society of Civil Engineers
Abstract: Fracture-dominated flow in fractured rocks is of interest in many areas of scientific and technical research. In contrast to the continuum approach, this study employed a discrete fracture model method to analyze water ...
A Shock Loss Reduction Method Using a Concave Suction Side Profile for a Zero Inlet Swirl Turbine Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A zero inlet swirl turbine rotor (ZISTR) works with axial inlet gas flow directly exhausted from a combustion chamber without any upstream vanes. The suction side trailing edge shock of the ZISTR generates a significant ...
