摘要： PROBLEM TO BE SOLVED: To estimate cumulative distortion present in a metal member such as an oscillation controlling damper or the like constituting a structure without ramoving the metal member from the structure or destroying the metal member. SOLUTION: The relation σ=f (ε, d) among stress σ, distortion ε, and a crystal grain diameter (d) and the relationship σ=g(H, d) among the stress σ, crystal grain diameter (d), and hardness H are previously obtained on a metal material with a yield point of the same level as that of the metal member constituting a structure at the time when the metal member does not have distortion, and the relationship ε=h (h, d) among the distortion ε, crystal grain diameter (d), and hardness H is obtained from the relationships. A micro test piece is collected from the metal member to measure actual hardness Ha and a crystal grain diameter da. Distortion εca is computed from ε=h(H, d) on the basis of the actual hardness Ha and crystal grain diameter da to estimate the cumulative distortion of the metal member as the distortion εca. Here, σmeans stress obtained by dividing a tensile force by a cross section reduced in a tensile test i.e., correction stress, and ε means a nominal distortion.
