N2 - In this study, a chisel tool’s tines which were subject to plastic deformation during tillage operations are considered. Stress distributions on the tools tines have been simulated using finite elements analysis (FEA) considering operational draft forces which have been obtained from the experimental study. Experimental material properties are assigned into the FEA simulations and all analyses conducted with due consideration to geometric and contact non-linearity in order to obtain more realistic results. According to the findings from simulations, it is shown that there is no plastic deformation failure evidence for conventional operational conditions. Subsequently, the limit draft force has been explored with setting up ‘What-If’ scenarios. Simulated visual outputs have been compared with physical deformation cases considering overloading conditions. Finally, it is concluded that the tillage tool considered within this paper was operated with very high draft force values which do not correlate with the design aim of the tool.
