Improving the Young's modulus of Mg via alloying and compositing – A short review

open access: yesJournal of Magnesium and Alloys, 2022
Lightweight, high-modulus structural materials are highly desired in many applications like aerospace, automobile and biomedical instruments. As the lightest metallic structural material, magnesium (Mg) has great potential but is limited by its low ...

Motives with modulus, I: Modulus sheaves with transfers for non-proper modulus pairs [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We develop a theory of modulus sheaves with transfers, which generalizes Voevodsky's theory of sheaves with transfers. This paper and its sequel are foundational for the theory of motives with modulus, which is developed in [KMSY20].

Temperature, Frequency and Young’s Modulus of a Wineglass

open access: yesInternational Scholastic Journal of Science, 2015
A crystal soda-lime wineglass, heated to temperatures ranging from 25 °C to 150 °C, was tapped and the frequency recorded. It was shown that the relative change in the frequency at different temperatures can be used to determine the effect of temperature

Evaluation of Subgrade Resilient Modulus and Modulus Ratio for Geotextile Reinforced Water Bound Macadam Road using Full-Scale Laboratory Accelerated Pavement Testing Set Up [PDF]

open access: yesJournal of Materials and Engineering Structures, 2022
Resilient modulus (MR) is a very important parameter for designing the flexible pavements. In the mechanistic pavement design, MR of pavement materials is used as an input parameter.

Determination of Constrained Modulus of Granular Soil from In Situ Tests—Part 1 Analyses

open access: yesGeotechnics, 2023
Assessing the constrained modulus is a critical step in calculating settlements in granular soils. This paper describes a novel concept of how the constrained modulus can be derived from seismic tests. The advantages and limitations of seismic laboratory

Influence of the Number of Parallel-Joints on Size Effect of Elastic Modulus and Characteristic Elastic Modulus

open access: yesFrontiers in Earth Science, 2022
The number of joints existing in the rock affects the elastic modulus of the rock, and the relationship has not been obtained. In this paper, 10 numerical models are established by numerical simulations to study the effect of the number of parallel ...
