To demonstrate the difference between 12 and 21. consider the following example in which a square composite plate containing unidirectional continuous T300 carbon fiber-reinforced epoxy is subjected to a uniaxial tensile load of 1000N. The plate thickness is 1mm. The length (L0) and width (W0) of the plate are 100mm each. Consider two loading cases, where 1. Load is applied parallel to the fiber direction 2. Load is applied normal to the fiber direction
