Compression tests and direct shear test of two types of railway ballast
Description
This data set contains measurement data from uniaxial compression tests and direct shear tests
conducted on two types of railway ballast.
For a detailed description of the experiments see:

experimental results and DEM model validation"

For the uniaxial compression tests, measured normal forces and vertical paths are provided.
The direct shear tests are conducted directly afterwards, i.e. the information for
one compression and one shear test are contained in only one file.
For the shear tests shear paths, shear forces and vertical path are provided.
At first the uniaxial compression test is carried out. At the end of this test, the normal load is equal to zero.
For the following direct shear test, the normal load is constant (according to the load specified in the file name)
and not recorded in the file.
The direct shear test starts, when the measured shear path is greater than zero.
Check the README.txt file for more information.
