The Alemnis High Strain Rate modules are high speed extension to the Alemnis Standard Assembly (ASA), the world’s most versatile micro mechanical testing system. Boost the performance of your control loop frequency, data acquisition rate, actuation speed, and cycling frequency by orders of magnitude. We offer two packages, Very High Strain Rates (VHS) and Ultra High Strain Rate (UHS), both of which  can be used together with the ASA in situ SEM, on synchrotron beamlines, in CT scanners, or stand-alone, with minimal  changeover times.

Nine orders of magnitudes of strain rates for indentation, tensile- and compression testing makes Alemnis the world’s fastest micro mechanical testing system, enabling unprecedented extreme experiments.

Alemnis provides the only high strain rate system that offers:

• Constant and controlled strain rates
• Continuous testing from quasi-static to high strain rates
• Read-out frequency of 1 MHz for displacement and load.
• Direct data analysis without complicated modeling or system assumptions

The Alemnis High Strain Rate module can also be combined with the High Temperature  and Low Temperature modules, pushing the limits of micromechanical testing at extreme conditions. [1] If used ex situ, High Strain Rate testing can also be combined with humidity control, which is particularly interesting for biomechanics and glass research. [2]
