- The crushable discrete-element model used here offers a novel combination of numerical efficiency and grading tracking capabilities and has enabled a systematic exploration and clarification of several questions related to the critical state theory. The results obtained support the hypothesis of a multiplicity of critical state lines in the compression plane for crushable granular materials showing they all belong to a unique critical state plane (CSP). The observation of the CSP has impacts for liquefaction susceptibility assessment (Ciantia and O’Sullivan 2020 10.1061/(ASCE)GM.1943-5622.0001707) and led to a Royal Society (IES\R1\201238) funded collaboration between Dundee University and Yokohama National University in Japan.
