To provide an evaluation method of tensile force applied to a soft material capable of suppressing variations in evaluation of elastic deformation or plastic deformation, an evaluation system of tensile force applied to the soft material, a control device, and a program.SOLUTION: A method for evaluating tensile force applied to a soft material includes the steps of: performing a plurality of cycles of loading and unloading of the tensile force relative to the soft material; obtaining a diagram 1 showing a correlation between the tensile force and elongation from an initial length of the soft material for each of loading and unloading of the tensile force; and comparing a diagram 11 of load at a first cycle and a diagram 12 other than that at a first cycle in the diagram 1 showing a correlation between the tensile force and the elongation.SELECTED DRAWING: Figure 2 【課題】弾性変形か塑性変形かの評価がばらつくのを抑制できる、軟質材に負荷される引張力の評価方法、軟質材に負荷される引張力の評価システム、制御装置及びプログラムを提供する。【解決手段】軟質材に負荷される引張力の評価方法は、軟質材に対して、引張力の負荷と引張力の除荷とを複数サイクル行うステップと、引張力の負荷と除荷との各々について、引張力と軟質材の初期長さからの伸びとの相関関係を示す線図１を取得するステップと、引張力と伸びとの相関関係を示す線図１において、１サイクル目の負荷の線図１１と、それ以外の線図１２とを比較するステップと、を備える。【選択図】図２
