RISEffect of Freeze–Thaw Cycles on Mechanical Strength and Microstructure of Silty Clay in the Qinghai–Tibet Plateau
Publisher: ASCE
Abstract: Freeze–thaw (F–T) cycles exert a significant effect on engineering activities in cold regions, thus attracting increasing attention around the world. In this study, a set of triaxial compression tests, scanning electron ...
Estimation of Moment-Independent Importance Measure on Failure Probability and Its Application in Reliability Analysis
Publisher: American Society of Civil Engineers
Abstract: Similar to the definition of the moment-independent importance measure on model failure probability, the authors define the moment-independent importance measure concerning the importance sampling method. After combining ...

Finite-Element Analysis of the Influence of Structural Parameters of a New-Type Wedge Ring Gasket on the Contact Pressure of the Main Sealing Surface
Publisher: ASCE
Abstract: As a kind of a detachable connection, flange sealing joints are widely used in chemical, nuclear power, and other industries. Research on new gaskets is one of the hotspots of flange connection technology. In this paper, ...
FrameGraph: A Scalable Performance Evaluation Method for Frame Structure Designs Using Graph Neural Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multilayer perceptron (MLP) and convolutional neural network (CNN) encounter a critical scalability issue when applied to the performance evaluation task for frame structure designs. Specifically, a model of MLP or CNN is ...
Imbedded Dual Number Automatic Differentiation for Computational Fluid Dynamics Sensitivity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dual number automatic differentiation was applied to two computational fluid dynamics codes, one written specifically for this purpose and one “legacy†fortran code. Results for the simple case of a fully developed ...
Erratum: “A Geometrically Nonlinear Shear Deformation Theory for Composite Shells” (J. Appl. Mech., 2004, 71(1), pp. 1–9)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wrong figure was used for Fig. 1 of the subject paper (1). Instead, this Fig. 1 should have been used, as was pointed out in the galley proof corrections sent to ASME on December 23, 2003.
Asymptotic Approach for Thermoelastic Analysis of Laminated Composite Plates
Publisher: American Society of Civil Engineers
Abstract: A thermoelastic model for analyzing laminated composite plates under both mechanical and thermal loadings is constructed by the variational asymptotic method. The original three-dimensional nonlinear thermoelasticity problem ...
