Material constants are one of the most important factors for determining the accuracy of analysis results and are essential for designers to make confident material decisions. For materials with non-uniform microstructures, such as fibre-reinforced composites, failure is initiated by many factors. Typical examples are delamination between layers, fibres, and matrices; fibre breakage; and crack initiation and propagation within the resin. Unfortunately, it is usually very difficult to measure these properties directly by physical testing because the fractures often occur at the microscale level. Delamination strength can be measured by double cantilever beam testing or end-notch bending beam testing. This is the largest scale problem and is easy to characterize directly by experiment.
