Install: Run I_Rheo_App_Installer.exe to install I_Rheo.
The Installer will automatically install MATLAB runtime.
NOTE: You will need administrator rights to run the MATLAB Runtime installer.
How to Use:
Aim: This program is designed to evaluate the Complex Modulus (G*) and
the Complex Viscosity by means of the Fourier transform of the
time-dependent stress and strain.
The steps are:
1) Import your stress and strain in the form
of a .txt file with 3 columns:
time (column 1), stress (column 2) and
strain (column 3).
2) Input the value of the stress at time = 0 &
Input the gradient of the stress at time =
infinity.
3) Input the value of the strain at time = 0 &
Input the gradient of the strain at time =
infinity.
4) Turn Oversampling on or off.
5) Run the FT, plots should be appear in the
lower axes.
6) Download the Complex Modulus in the
form of a .txt file with three columns:
Frequency (column 1), G' (column 2)
& G" (column 3).
7) Download the Complex Viscosity in the
form of a .txt file with two columns:
Frequency (column 1) & Viscosity
(column 2).
