A method was investigated to identify the material constants of some domains packed small balls in a reactor vessel. The reactor vessel had been used for the purification of hydrogen to separate hydrogen from feed gas. The vessel consists of a long vessel including seven pipes and small catalyst balls, and then the space between those pipes and the vessel is filled with those balls. The domain packed the balls was assumed by a continuum and was divided by ten parts. We examined the validity of the proposed identification method by numerical simulations. The bending strains of seven pipes in the vessel were measured by 3-points bending test of the vessel model and were calculated by finite element analysis. The calculated strains had the good agreement with the measured ones.
