The article presents a computer model considering two caterpillars, resting on elastic-plastic sub-soil, with standard Mohr-Coulomb yield conditions, allowing for computer simulation of the behavior of the system up to achievement of ultimate limit state. The results of the above model are treated as the reference for a simplified Analytical Models of estimating the limit state, which might be used in design procedures. In turn, these Analytical Models are enhancements of previously presented one. The most important results concluding form the Analytical Model are simple interaction formulas, in the space of moments acting on the machine-subsoil system, limiting a domain of safety in given soil conditions.}, type={Article}, title={Stability analysis of heavy machinery moving on weak subsoil. 3D FEM model vs. analytical models}, URL={http://journals.pan.pl/Content/130810/ACE_2024_01_38.pdf}, doi={10.24425/ace.2024.148934}, keywords={3D FEM model, analytical models, geotechnical engineering, interaction curves, subsoil – machine interaction, working platform}, }
