In this study, a MDS specimen which a uniform distribution of shear stress can be realized by using comparatively simple testing device is studied for impact shear deformation of TRIP steel. The shape and size of the specimen for an appropriate measurement of its impact shear deformation are determined by FEM. Then, a rate sensitivity on shear deformation of TRIP steel is investigated by measurement of shear deformation at various strain rate using a conventional material testing machine and the split Hopkinson pressure bar method.
