Improving the mechanical properties of the material surface has been the main aim of the researchers for a long time. Utilizing of mechanical treatment procedures, such as direct impact, has been widely used for the bulk materials, but determination of the change in the mechanical properties of impacted material has not been exactly investigated. The main novelty of this paper is the determination of the effect of mechanical treatments on the mechanical properties of bulk materials. For this purpose, the new developed combined algorithm of modified dimensional analysis and minimum resultant error methods were emerged with FEA and experimental data. The finite element analysis (FEA) included the analysis of the impact with nanoindentation in a continued procedure to allow the investigation of the impact on the results of the nanoindentation. Previously, this trend had not been applied to analyze such phenomenon. The challenges of preparing a perfect analysis model to suit the nanoscale process (nanoindentation) and macro process (ball impact) were another investigation field of this research work. The result of this research was a complete calculation of the parameters of Johnson–Cook constants for titanium (Ti) bulk material including the most important strain rate coefficient (C). Comparison of Ti mechanical characteristics shows high improvement in yield stress (24%) against lower change in the elastic modulus (1.2%).
