Expert Commentary
In-Plane Shear Influence: ISO 14126 (Method 1 or 2) is the European counterpart to ASTM D6641. It focuses heavily on the Combined Loading of composites. To meet the accuracy requirements for Compressive Modulus, back-to-back strain measurement is essential. This is to ensure that Euler Buckling isn’t occurring mid-test. The MTO Compression Fixture must provide a rigid, friction-free environment. If the fixture’s sliding components bind, the load cell sees the friction force + specimen force, leading to a High strength reading. Using Strain Gauges is the gold standard here, but TestVE with a mirror-system (to see both sides of the specimen simultaneously) is a modern alternative that significantly reduces the cost per test by eliminating the need for expensive, single-use gauges.
