The paper deals with the pulverization (fracture) model that is not based on soil elastic properties but on the physical processes of the wedge interaction with soil. The presented model agrees with the experimental data better than other models, including those based on soil elastic properties, and the tests of flat tillage tools with a variable cutting angle have proved this.doi:10.1016/j.proeng.2015.12.010 fatcat:mmtb3atghrdnhl2mk2ksutwkji
