... for finite element software is a stumbling block for the validation of a rock model, which remains questionable, as the actual behaviour of the rock masses is highly non-linear. Neither in-situ expansion testing nor uniaxial compression testing directly measures a single modulus representative of the rock...

Therefore, in this paper we present an example to combine these two methods to study the X-ray CT technology-based finite element simulation of coal samples under uniaxial compression. The micro FEM simulation agrees well with the experiments and theory, which present...
