Testing of sandwich elements according to DIN EN 14509

With the universal testing machine inspekt duo 10 kN, bending tests as well as compression tests and tensile tests according to DIN EN 14509 can be performed. The 4-point bending bench has freely mounted supports with load distribution plates that ensure optimum force application in the sandwich element to be tested. For precise determination of the deflection, an incremental measuring probe with 0.5µm measuring accuracy is attached to the lower bending beam.

Testing the transverse tensile strength perpendicular to the element

Tensile tests according to DIN EN 14509 procedure A.1 are realized in this test setup via a lifting device to be installed in the bending bench. This allows many different test applications to be implemented without complicated modification or removal of the heavy bending bench. After the tensile test, the material and component testing software LabMaster automatically calculates characteristic values such as the transverse tensile strength of the element f_Ct or the tensile modulus of elasticity of the core E_Ct.

Testing the compressive strength and modulus of the core material

The corresponding pressure plates can also be easily installed in the bending bench for compression testing according to DIN EN 14509 procedure A.2. The lower compression plate is mounted movably in this case. LabMaster again provides the required results such as compressive strength of the core material f_Cc and compressive modulus of the core E_Cc.
