The basic properties of damping capacity of the industrial materials are examined in this investigation. The relation between damping capacity and rise surface temperature buckling stress, logarithmic decrement or shear modulus is clarified. All the tests are observed using several high polymers and metals. The materials tests performed torsion, rotary bending, buckling and dynamic torsion. The conclusion obtained as follows; (1) Relation between damping capacity ⊿W and maximum shearing stress τ_<max> are ⊿W=J(τ_<max>)^m. The coefficients of J and m are determined as peculiarity of industrial materials. (2) The materials with high damping capacity are tended to high surface temperature. (3) The materials of high damping capacity show low bucking stress. (4) The high polymer materials with high dampig capacity has high logarithmic decrement and low shear modulus.
