Data Augmentation Based on Image Translation for Bayesian Inference-Based Damage Diagnostics of Miter Gates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural health monitoring (SHM) data is the essential foundation for any SHM structural integrity assessment, including large civil infrastructure such as the miter gate application in this work. For some applications, ...
A Local Material Basis Solution Approach to Reconstructing the Three Dimensional Displacement of Rod Like Structures From Strain Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new approach for determining threedimensional global displacement (for arbitrarily sized deformation) of thin rod or tetherlike structures from a limited set of scalar strain measurements. The approach ...
Nonlinear Vibration of Orthotropic Rectangular Membrane Structures Including Modal Coupling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The membrane structure has been applied throughout different fields such as civil engineering, biology, and aeronautics, among others. In many applications, large deflections negate linearizing assumptions, and linear modes ...
Uncertainty Quantification of a Machine Learning Model for Identification of Isolated Nonlinearities With Conformal Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural nonlinearities are often spatially localized, such joints and interfaces, localized damage, or isolated connections, in an otherwise linearly behaving system. Quinn and Brink (2021, “Global System Reduction Order ...
Uncertainty-Aware, Structure-Preserving Machine Learning Approach for Domain Shift Detection From Nonlinear Dynamic Responses of Structural Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex structural systems deployed for aerospace, civil, or mechanical applications must operate reliably under varying operational conditions. Structural health monitoring (SHM) systems help ensure the reliability of ...
Surrogate Modeling of Nonlinear Dynamic Systems: A Comparative Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surrogate models play a vital role in overcoming the computational challenge in designing and analyzing nonlinear dynamic systems, especially in the presence of uncertainty. This paper presents a comparative study of ...
