Matlab toolbox for processing of GREAC cell data

This report provides the documention for a Matlab toolbox that has been developed at FFI. The purpose of the toolbox is to process and analyse raw data from a GREAC cell test, in order to extract material models and parameters for the concrete being tested. It is optional whether to do the calculations with the thick cylinder theory approximation, or find a finite element solution. A brief introduction to the theory of finite element codes is also given.
