RelaxPy: Python code for modeling of glass relaxation behavior

SoftwareX, 2018
The degree of relaxation in any glass sample is a governing property in every property of the glass. It plays an important role in every major glass product commercially available, but has required individual groups to develop their own relaxation codes.

Reconstruction of sparse wavelet signals from partial Fourier measurements

, 2015
In this paper, we show that high-dimensional sparse wavelet signals of finite levels can be constructed from their partial Fourier measurements on a deterministic sampling set with cardinality about a multiple of signal ...

Inverse spectral problem for glassy state relaxation approximated by Prony series

The stretched exponential relaxation function is used to analyze the relaxation of the glassy state data. Due to the singularity of this function at the origin, this function is inconvenient for data analysis. Concerning this, a Prony series approximation of the stretched exponential relaxation function (J. Mauro, Y. Mauro, 2018), which is the extended

Short-Term Creep Experiment of Cement Asphalt Mortar and Its Numerical Simulation

Advances in Materials Science and Engineering, 2016
In order to investigate the creep performance of cement asphalt mortar (CA mortar), the field sampling of CA mortar cylinder samples was produced, and all samples were tested on WDW series electric universal testing machine by using uniaxial static creep

On the analytical determination of relaxation modulus of viscoelastic materials by Prony's interpolation method [PDF]

A computer implementation to Prony's curve fitting by exponential functions is presented. The method, although more than one hundred years old, has not been utilized to its fullest capabilities due to the restriction that the time range must be given in ...
