Full-field measurement and fracture and fatigue characterizations of asphalt concrete based on the SCB test and stereo-DIC

, 2020
This study investigated the full-field displacement and strain fields of asphalt concrete under semi-circular bending (SCB) through the stereo-digital image correlation (stereo-DIC) technique. Fracture and fatigue tests were conducted with two high-speed

In-situ measurement of nominal compressive elastic modulus of interfacial transition zone in concrete by SEM-DIC coupled method

, 2020
Due to the small dimensions of interfacial transition zone (ITZ) in concrete, the measurement of ITZ is subjected to difficulties of deformation measuring at macro-scale and loading at micro-scale.

Fit for a Bayesian: An Evaluation of PPP and DIC for Structural Equation Modeling

Structural Equation Modeling: A Multidisciplinary Journal, 2017
Despite its importance to structural equation modeling, model evaluation remains underdeveloped in the Bayesian SEM framework. Posterior predictive p-values (PPP) and deviance information criteria (DIC) are now available in popular software for Bayesian ...
