Characteristic Analysis of Dynamic Modulus for High Modulus Asphalt Concrete
Applied Mechanics and Materials, 2014In order to analyze the characteristics of high modulus asphalt mixture dynamic modulus, Universal Testing Machine (UTM-25) was used for dynamic modulus test of three kinds of mixtures, which were PR Module modified asphalt mixture and PR PLAST.S modified asphalt mixture and virgin asphalt mixture, to investigate dynamic modulus and phase angle at ...

Dynamic on-line sensing of sheet modulus of elasticity
Conference Record of 2008 54th Annual Pulp and Paper Industry Technical Conference, 2008This paper proposes and evaluates a methodology for robust, on-line estimation of the modulus of elasticity of an elastic strip transported through a multi-span system. The estimation algorithm is based on a previously developed robust sensorless sheet tension estimation, and the computation of speed draws using 1024-pulse encoders operating in 4x mode.

In that the elastic constants, Cij, which may be used to calculate the bulk, shear, and Young’s moduli, as well as the Debye temperatures of polycrystalline materials, are related to the electronic properties and in some cases have first been calculated from principles, they form a bridge between the mechanical properties of materials and their ...

Note on Biot's Dynamic Modulus
The Journal of the Royal Aeronautical Society, 1941In reference 1 Biot has given a simple and valuable formula for what he calls the “ dynamic modulus “ of a flywheel system or airscrew in terms of resonance and anti-resonance frequencies. The resonance frequencies are the natural frequencies when the systems are free, and the anti-resonance frequencies are the natural frequencies when the end of the ...

Dynamic modulus measurement using the Dynamic Mechanical Analyzer
The Journal of the Acoustical Society of America, 2006The Navy has used the Dynamic Mechanical Thermal Analyzer (DMTA) as a tool to characterize material properties over the last 20 years. It is now evaluating the Dynamical Mechanical Analyzer (DMA) as a replacement for the DMTA, with the goal to insert it into operation in 2006 with minimal disruption to current acquisition programs.

Calibration of dynamic modulus predictive model
Construction and Building Materials, 2016Abstract The aim of the present study is the evaluation of the Witczak 1-37A, Bari & Witczak, NCHRP 1-40D and Hirsch models for the estimation of dynamic modulus ( E ∗ ) and the subsequent calibration of the model to best fit with laboratory reference data of the material under investigation.

The dynamic shear modulus of marine sediments
The Journal of the Acoustical Society of America, 1988The dynamic shear modulus of marine sediments (μ) as a function of overburden pressure (p) and voids ratio (e) can be represented approximately by the expression μ=μ0(p/p0)n ×exp(−Γe), where μ0, n, and Γ are constants. Available laboratory results for sands, silts, and clays over a pressure range of 24 to 700 kPa and a voids ratio range of 0.35 to 1.5 ...

Modulus reduction dynamic analysis
2010A semi-analytical method of dynamic analysis, capable of predicting both the magnitude and pattern of earthquake induced deformations, is presented. The analysis is based on a modulus reduction approach which uses a reduced modulus to simulate the softening induced in soils during cyclic loading.
