Tittle:
Novel method for non-destructive determination of mechanical material properties
Summary:
A team of German scientists developed a method and device for a non-destructive determination of mechanical properties of materials.
A Cooperation with industrial partners is sought in the frame of a research cooperation agreement or on the basis of a license agreement.
Description:
The non-contact determination of deformation and flow properties of materials is a technological challenge and thus represents an important field of study in material engineering. At present, no satisfactory solution is available.

The rheometry offers the possibility to characterize materials concerning their different loads (e.g. shear deformation, tensile deformation and bending deformation). These rheological properties are determined by applying mechanical stress which largely causes destruction of the probed component. In addition, it is a time consuming measurement which requires the preparation of specimens. The practical implementation of rheological investigations is therefore complicated and for industrial uses not economical.

The offered innovation presents a method that addresses the aforementioned thematic and is suitable for the investigation of a variety of elastic and viscoelastic materials as well as glasses and liquids. It is using the acoustically induced laser scattering method (ALS) that avoids these disadvantages by applying the principle of the acousto-optical modulation. By an appropriate arrangement of an ultra-sonic source a sonic grid diffracting laser light is generated in the material. By exclusively using the diffraction peak of the laser light in a test object the invention enables new possibilities of non-invasive determination of relevant rheological and other mechanical properties. With this method a non-destructive measurement with little technical effort and very short measuring times gets possible. Especially it is suitable for in situ measurements in contrast to conventional rheometers.
Thus, the invention has a big market potential in the fields of materials science, materials testing, material engineering and quality assurance.

To make the developed method and device fit for practical applications the scientists are now looking for industrial partners interested in a common further development on the basis of a research cooperation agreement or in a license agreement.
