Gibbs Sampling for Damage Detection Using Complex Modal Data from Multiple Setups
Publisher: ASCE
Abstract: This paper presents a novel Gibbs sampling approach for structural health monitoring (SHM) with detection of structural changes/damages using incomplete complex modal data measured with a limited number of sensors. The ...
Dependence of Critical Stress Intensity Factor on Crack Depth From the Loading Boundary of Crystalline Silicon
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, an atomistic scale investigation is done on crystalline silicon to understand the effect of crack depth from the loading (pulling) boundary on the critical near-tip state of stress. For various depths ...
Multiclass Damage Identification in a Full-Scale Bridge Using Optimally Tuned One-Dimensional Convolutional Neural Network
Publisher: ASCE
Abstract: In this paper, a novel method is proposed based on a windowed one-dimensional convolutional neural network (1D CNN) for multiclass damage identification using vibration responses of a full-scale bridge. The measured data ...
