Flow Induced Crystallization: General description¶
Purpose¶
Module for handling data from start up of shear and extensional flow experiments with flow induced crystallisation.
Data Files¶
The first line of the file should contain the sample parameters separated by semi-colons (
;
). It may contain any number of parameters which will be read and saved as file-parameter in RepTate.Then the data columns should appear, separated by spaces or tabs.
.shearxs
extension¶
Text files with .shearxs
extension should be organised as follows:
.shearxs
files should contaion at least the parameter values for the:shear rate, \(\dot\gamma\)
shear end time, \(t\)-stop
temperature, \(T\)
5 columns separated by spaces or tabs containing respectively:
time, \(t\),
shear stress growth function, \(\sigma^+(t)\),
nucleation rate, \(\dot N(t)\),
crystal fraction, \(\phi_X(t)\),
nucleation density, \(N(t)\),
Other columns will be ignored. A correct .shearxs
file looks like:
gdot=0.1;tstop=50.0;T=0.0;
t sigma_xy Ndot phi_X N
