Testing Terminology
The UniVert is designed to apply uniaxial compressive and tensile forces to a variety of materials.
This includes soft metals, plastics, and composites as well as biological materials.
Multiphase Test Cycles
In order to properly characterize and test a specimen, it is often necessary to load it to different
degrees and at different rates. There are three main reasons for doing this:
Preconditioning - Especially for biological specimens, the goal of preconditioning is to restore a
specimen to its physiological or in vivo state. During the process of specimen storage and
preparation, a specimen may swell, dry out, have its material fibers realign, or its molecules
reorganize. It may take multiple preconditioning cycles for a specimen to be restored to its natural
state.
Reproducing Physiological Conditions During Testing - By applying various loads and load
rates, natural expansion and contraction of a specimen can be reproduced (for example, the
pulse pressure in an organ). In as much as the physiological conditions can be recreated, the
specimen can be tested in a more realistic state.
Varying Test Conditions - Variable loads and rates allow you to create a variety of test profiles
to best study your specimen.
