Critical Softening Radius of a Development Heading Causing Rock Bursts
Publisher: ASCE
Abstract: Generally, prevention and control methods are adopted to reduce the possibility of regional stress-field-induced impact bursts in pressure relief engineering. However, such methods lack theoretical support and may inadvertently ...
Reducing Geometric Uncertainty in Computational Hemodynamics by Deep LearningAssisted ParallelChain MCMC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational hemodynamic modeling has been widely used in cardiovascular research and healthcare. However, the reliability of model predictions is largely dependent on the uncertainties of modeling parameters and boundary ...
Mesoscale Simulation of the Effect of pH on the Hydration Rate, Morphology, and Mechanical Performance of a Calcium-Silicate-Hydrate Gel
Publisher: ASCE
Abstract: The pH plays a key role in the hydration process of cement clinker and thus determines the morphology and mechanical performance of cement-based materials. Herein the effect of pH on the nucleation rate, morphology, and ...
Dielectric Model of Asphalt Mastics Considering Temperature Influence
Publisher: ASCE
Abstract: As an important stage in the three-stage dispersion system of asphalt mixtures, the structure and properties of asphalt mastics have a significant impact on the road performance and dielectric properties of asphalt mixtures. ...
Assessing Interfacial Bonding Performance of PVA Fiber and Cement Hydration Products: An Atomic Simulation
Publisher: ASCE
Abstract: The composition and properties of the interface are the key points which determine the properties of fiber-reinforced cement–based composites. The bonding performance between fibers and different hydration products at the ...
Study on Dielectric Properties of Asphalt Mixtures Considering the Effects of Relative Humidity
Publisher: American Society of Civil Engineers
Abstract: Ground penetrating radar (GPR) technology is used for nondestructive testing of roads. It relies on the processing and analysis of electromagnetic waves reflected due to the differences in dielectric properties encountered ...
Polymer Enhancement Mechanisms in Cementitious Materials: Insights from Atomistic Simulation
Publisher: ASCE
Abstract: The mechanical properties of organic/inorganic composites at a macroscopic level are largely determined by the interaction mechanisms at the interface. However, there have been limited microscopic studies on these interactions. ...
Composite Dielectric Model for Cement Concrete Considering Water Saturation
Publisher: American Society of Civil Engineers
Abstract: Water has a significant impact on the dielectric constant of materials. As a multiphase composite material, the effect of water content must be taken into account when modeling the composite dielectric of cement concrete. ...
