In this paper, it is reported that an analyzing method of the elasticity and other deformation characteristics can be established by the reaction force of indentation testing. This method is adopting the analyzing procedure of indentation force to derive the deformation characteristics of materials in the ball indentation testing which is one of most fundamental testing. A flow of analyzing procedure of various behavior on the deformation of materials is also shown for the profile of variation of reaction force due to indentation test. Especially, the evaluation possibility of various behaviors included in complicated and nonlinear relationship of a profile of the reaction force due to the indentation test is shown by the inverse-analytical comparison between the force and the proofed indentation theories.
