Application of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation [PDF]
Numerical Methods in Civil Engineering, 2014 In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship.

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 To better control the strength and deformation of the roadbed, a constitutive model of rockfill was established based on property‐dependent plastic potential theory for geomaterials. The effect of the particle gradation on the anisotropy was described in the model.
