   Fiber Orientation
   In anisotropic composites, such as unidirectional laminates, the mechanical response is highly dependent on the alignment of the fibers relative to the applied load. A key performance metric is the Off-Axis Strength Ratio (OASR), which quantifies the degradation of strength when the load is applied at an angle $\theta$ relative to the fiber axis.
   For simple laminae, the shear strength ($\tau_{12}$) often decreases proportionally to $\theta^3$ for angles less than $…
