The most common and general test used to understand the behavior of materials under load is a tensile test. When loaded, the specimen is deformed as well as UTM. The construction of the device must be stiff enough to ensure that the influence of UTM deformations on the specimen is minimal. In program Abaqus, many linear and volume model of the device construction has been made. Using the FEM, UTM strength analyses were performed. Strength analyses confirmed the rigidity of the device for performing tensile tests up to 30 kN. Both, middle beam and lower beam are adapted to attach different mounts of measuring cells, grips and other accessories. Because of its generality, UTM is suitable for a wide range of different tests.
