The Shore hardness test has been used commonly as a technique of basic hardness measurement. In order to deepen the basic knowledge of the Shore hardness test, the motion of the hammer was numerically investigated using an elastoplastic finite-element method, and was also experimentally studied using a laser doppler vibrometer. By comparing the numerical results with experimental results, it has been clarified that the Shore hardness is significantly influenced by the elastic deformation of the hammer at impact. The efect of deformation of the hammer can be described by the model where the hammer is dealt with a small number of point masses connected by springs in a series. The numerical results show that the impact force increases with increasing hardness of specimens and the force exceeds 1000 times the weight of the hammer.
