LABORTECH – World Leader in HOPKINSON High-Rate Impact Testing Systems

LABORTECH is a world leader in the design and manufacture of HOPKINSON High-Rate Impact Testing Systems. High strain rate properties play a key role in the design of safety principles used in transportation, protective system developers and the military.

Our systems, known as HP Test, are configurable for a wide range of strain rates from 100 to 10,000 s⁻¹. This allows us to tailor test conditions to closely simulate real-world conditions. These systems offer infinite variability in clamping any test specimen, data collection and evaluation, and temperature control on the test specimen.

This sophisticated approach to high strain rate testing provides researchers and developers with fast and accurate results. Our models are able to capture the material’s energy absorption, deformation, and viscoelastic response as a function of strain rate and/or temperature. This provides reliable and detailed information needed for the development and optimization of materials in demanding applications.
