RISPhysics-Informed Machine Learning for Hybrid Digital Twin–Enhanced Damage Detection and Localization
Publisher: American Society of Civil Engineers
Abstract: AbstractIn structural health monitoring (SHM), structural damage detection and localization
have made significant advances with deep learning–based methods. While finite element
model (FEMs) have been employed to simulate ...
Arbitrary-Order Sensitivity Analysis in Phononic Metamaterials Using the Multicomplex Taylor Series Expansion Method Coupled With Bloch’s Theorem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Phononic metamaterials (PMs) exhibit frequency ranges at which elastic waves are attenuated called band gaps. However, this phenomenon is highly sensitive to geometrical variations and the unit cell’s mechanical properties. ...
HYPAD-UQ: A Derivative-Based Uncertainty Quantification Method Using a Hypercomplex Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A derivative-based uncertainty quantification (UQ) method called HYPAD-UQ that utilizes sensitivities from a computational model was developed to approximate the statistical moments and Sobol' indices of the model output. ...
Theoretical and Experimental Evaluation of Two Roadway Piezoelectric-Based Energy Harvesting Prototypes
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of a theoretical and experimental study aiming to develop a stress-based roadway energy harvesting system. It describes two prototypes using piezoelectric elements. Prototype I consisted of ...
