In the paper, effect of strain rate on shear strength of phenolic resin adhesive for jointing steel plates was considered. Firstly, static shear strengths of the adhesive were measured using double lap specimens under several strain rates and temperatures, since mechanical properties of polymeric material highly depends on both strain rate and temperature. The master curve of shear strength was determined from the experimental results according to time-temperature dependence equivalent law for thermo-viscoelasticity. To confirm the validity of the law for shear strength, impact tests were conducted. Then it was clarified that shear strength of phenolic resin adhesive under different strain rate and temperature can be predicted using the master curve given from results of static tests.
