Mechanical characterization

Deformation analysis of bonded shear sample using gray scale correlation

Mechanical characterization of an adhesive bulk sample
To characterize the adherence strength values, mechanical parameters are determined by destructive testing using a multi-axis material testing machine. In this study, both uniaxial load cases, such as tension, pressure, bending, or torsion, as well as multi-axial overlaps in the form of tension/pressure-torsion loads/ stresses, can be measured. Available conditioning chambers also make it possible to determine the strength values influenced by temperature and humidity.
Three-dimensional deformations at the surface can be recorded during the test and then analyzed in combination with an optical measuring system based on gray value correlation.
