The dynamic stiffness modulus measurement is to determine the relationship between maximum applied stress and maximum strain response performed by measuring the displacement of tested system. The test is conducted using MTS Landmark servohydraulic testing system of 100 kN, special grips for fixing the sample and RTSS videoextensometer in accordance with modified method:
EN 12697-26 Bituminous mixtures – Test methods – Part 26: Stiffness
As part of the testing of the PM&VL7 research line, Flex&Robust composites were examined.

The goal of the test is to determine the vertical load capacity and load deflection characteristics of brackets subjected to vertical load. Vertical load capacity shows the ability of a bracket to withstand stresses during use.

The goal of the test is to determine the strength of corners of window/casement frame when it is subjected to compression bending test. The strength of corners shows the ability of a window/casement frame to withstand stresses during installation and use.

The goal of the test is to determine the in-plane initial shear strength of bed joints made with polyurethane injection in masonry. The specimens are tested in shear under four-point load with precompression perpendicular to the bed joints.

Shear resistance shows the ability of a joint to withstand in-plane stresses during use.
