Creep: General description

Purpose

Application to Analyze Data from Creep experiments

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.

.creep extension

Text files with .creep extension should be organised as follows:

  • .creep files should contain at least the parameter value for the:

    1. Applied stress stress

  • 2 columns separated by spaces or tabs containing respectively:

    1. time, \(t\),

    2. strain, \(\gamma\),

A correct .creep file looks like:

stress=10;chem=PE;label=CM3;T=150;
t         strain          stress      T
s         -           Pa          C
1E-3  1.413E-5        10          149.9
1E-3  -9.419E-6       10          149.9
1E-3  -2.826E-5       10          149.9
...   ...         ...     ...

log(J(t))

BaseApplicationCreep.viewJt()[source]

Compliance \(J(t)=\gamma(t)/\sigma_0\) (where \(\sigma_0\) is the applied stress in the creep experiment) vs time \(t\) (both axes in logarithmic scale)
