Slow dynamic nonlinearity in unconsolidated glass bead packs [PDF]
Phys. Rev. E 101, 012901 (2020), 2019 Slow dynamic nonlinearity describes a poorly understood, creep-like phenomena that occurs in brittle composite materials such as rocks and cement. It is characterized by a drop in stiffness induced by a mechanical conditioning, followed by a log(time) recovery. A consensus theoretical understanding of the behavior has not been developed.

Data-driven prediction of room temperature density for multicomponent silicate-based glasses [PDF]
arXiv, 2022 Density is one of the most commonly measured or estimated materials properties, especially for glasses and melts that are of significant interest to many fields, including metallurgy, geology, materials science and sustainable cements. Here, two types of machine learning (ML) models (i.e., random forest (RF) and artificial neural network (ANN)) have ...

Nonlinear quasilocalized excitations in glasses. I. True representatives of soft spots [PDF]
Phys. Rev. E 101, 032130 (2020), 2019 Structural glasses formed by quenching a melt possess a population of soft quasilocalized excitations --- often called `soft spots' --- that are believed to play a key role in various thermodynamic, transport and mechanical phenomena. Under a narrow set of circumstances, quasilocalized excitations assume the form of vibrational (normal) modes, that are

Nanoionomer: Evaluation of microleakage
Journal of Indian Society of Pedodontics and Preventive Dentistry, 2011 Background: Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic
