Dynamic Modulus of Poroelastic Materials

Journal of Applied Mechanics, 1989
A simple mathematical formula is proposed to predict the fluid damping effects in poroelastic materials. Biot’s poroelasticity equations are solved to obtain the response of poroelastic materials undergoing harmonic tension-compression and bending deformation.

Mesoscale structure-based investigation of polyurea dynamic modulus and shock-wave dissipation

, 2020
Polyurea is a block copolymer with excellent shock absorption. It has a unique phase separation structure, yet there are few reports on how the mesoscale structure affects the dynamic mechanical properties.

Dynamic Modulus of Asphalt Mixtures

Transportation Research Record: Journal of the Transportation Research Board, 2015
Mix properties that deviate appreciably from the design properties during the production and construction of asphalt mixtures can lead to premature pavement distress or even failure. The objective of this study was to quantify the differences in the dynamic modulus of specimens prepared during design, production, and construction ...

A new dynamic modulus predictive model for asphalt mixtures based on the law of mixtures

, 2020
The dynamic modulus (|Em*|) of asphalt mixtures is one of most fundamental mechanical parameters used in flexible pavement design, which has been extensively estimated through various predictive models.

Predicting the Resilient Modulus of Asphalt Concrete from the Dynamic Modulus

Transportation Research Record: Journal of the Transportation Research Board, 2007
The NCHRP 1-37A Guide for Mechanistic-Empirical Design of New and Rehabilitated Design Structures introduces the dynamic modulus as the material property to characterize asphalt concrete. This is a significant change from the resilient modulus used in the previous AASHTO pavement design guide. This paper presents an analytical method of calculating the

Integrated finite element and artificial neural network methods for constructing asphalt concrete dynamic modulus master curve using deflection time-history data

, 2020
Dynamic modulus |E*| is one of the essential material properties input in the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG).

Backcalculation of dynamic modulus from resilient modulus test data

Canadian Journal of Civil Engineering, 2011
For the past few decades, the stiffness of asphalt material has been commonly characterized by means of resilient modulus. However, the resilient modulus is not a fundamental material property, and hence, the concept of resilient modulus has been subsequently diminished in the latest Mechanistic-Empirical Pavement Design Guide (MEPDG).
