MHDA Three-dimensional Dynamic Deformation Measurement

As an initially independently-developed dynamic deformation measurement system，MHDA offers a full-field, non-contact measurement of deformation, vibration, strain on almost any material. The technique can be used for many tests including tensile, torsion, bending and combined loading for both static and dynamics applications. The method can be applied from very small (micro) to large testing areas – and the results are readily comparable with FEA results or strain gauges.
