Numerical Modelling | RockEng
In numerical modeling, rock mass behavior can be simulated with varying levels of detail and complexity, ranging from simpler linearelastic to more complex plastic models, with the option for defining postpeak material parameters. Our modelling experts work with models across this spectrum of complexity, ensuring that numerical inputs are justified by the available data and simulations tools ...

Special Issue "Numerical Modeling in Civil and Mining ...
Numerical modeling is largely used in geotechnical engineering to understand the responses of infrastructures in civil and mining engineering. Many homemade or commercialized numerical codes are available to handle with different geotechnical problems. For some, numerical modeling can be used as a useful tool to obtain qualitative results, showing some general idea or trend. For some others ...
