Micro Tensile Machine

The Micro Tensile Machine is a versatile device, which allow performing tensile and compression experiments on mm to cm sized specimens. Various load cells and grips are available to match the sample shapes. The machine was originally designed for use at the Materials Science beamline of the SLS.
The steering software was developed in-house using LabVIEW. Apart from conventional displacement controlled tension or compression tests other, more complex tests can be triggered interactively, such as strain rate jump tests, repeated stress relaxation, stress reduction tests, creep, etc.
