DOI: 10.1080/15376494.2021.1980923
Abstract: In the computational damage mechanics, the coupled elastoplastic damage model involves a nonsymmetric tangent operator. This implies that a sparse matrix solver is needed, which means more computat... read more here.

DOI: 10.1155/2021/9991251
Abstract: More deep tunneling projects will be constructed due to the increasing demand of underground energy and resource. The zonal disintegration phenomena are frequently encountered with the surrounding rock of deep tunnels. To explain the mechanisms… read more here.

DOI: 10.18690/actageotechslov.15.2.38-46.2018
Abstract: Deep-buried engineering and test results show that hard rocks behave as part of an elastoplastic damage coupling process. The coupling effect can contribute to the weakness of the surrounding rocks and the extension of the… read more here.
