Real-time Prediction of Dynamic Systems Based on Computer Modeling
… cooperative autonomous vehicle system and the full-field measurement system. For the cooperative autonomous vehicle system a novel parallel grid-based RBE technique is firstly proposed. The formulations are derived by identifying the parallel computation in the prediction and correction …

An Analysis of Non-Uniform Stress States in Finite Thin Film/substrate System: The Need of Full-Field Curvature Measurements
… dependence on curvatures, which make full-field measurement a necessity for the experimental inference of such stresses. We also extend the methodologies to the case that of single thin film/substrate subjected to non-uniform anisotropic misfit strain. The film stresses and system …

Full Field Reconstruction Enhanced With Operational Modal Analysis and Compressed Sensing for General Dynamic Loading
… several discrete locations. The accuracy of the measurements varies with the location and orientation of the sensors. Practically, it is not possible to place sensors at all the critical locations for different excitations. Therefore, an approach that derives the full field response using a …

Image-Based Geotechnical Constitutive Model Parameter Calibration
… applied stresses. While necessary due to current measurement technique limitations, there is evidence that this assumption is somewhat at odds with reality beyond small strains. Often, when conventional tests are ill-suited for calibrating a particular material parameter, multiple model-specific …

Stress and creep damage evolution in materials for ultra-supercritical power plants
… towards t he weld root region and these were not fully relieved by the applied PWHT. In both conditions substantial tensile direct and hydrostatic stresses existed across the HAZ, including the fine-grained and intercritically-annealed regions, where premature Type IV creep failures manifest in …

Evaluation of optical techniques applied to online turbomachinery blade vibration measurements
… for the use of non-contact methods. Contact measurement techniques for turbomachinery blade vibration analysis typically involve the use of strain gauges and accelerometers. These present some complications when analyzing rotating machinery. Being contact in nature, mass loading can affect …
