Abstract: An example method includes positioning a mass at a height opposite a modulator characterized by a particular strain rate and support by a carrier moveably disposed opposite the mass. The method also includes releasing the mass such that the mass impacts the modulator, and an additional component connected to the carrier causes failure of a sample of material. The method further includes determining a displacement of the carrier corresponding to failure of the sample, determining a force applied to the modulator by the mass and resulting in failure of the sample, and determining at least one of a dynamic strength of the sample and a dynamic modulus of the sample. In such a method, the dynamic strength is based on the force applied to the modulator and the strain rate. Additionally, the dynamic modulus is based on the displacement of the carrier and the strain rate.
