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:

  1. shear rate, \(\dot\gamma\)

  2. shear end time, \(t\)-stop

  3. temperature, \(T\)

• 5 columns separated by spaces or tabs containing respectively:

  1. time, \(t\),

  2. shear stress growth function, \(\sigma^+(t)\),

  3. nucleation rate, \(\dot N(t)\),

  4. crystal fraction, \(\phi_X(t)\),

  5. 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
