Impact & resist - sunlight (inverse & orbit1 mix)

The momentum required for a wood 2x4 missile to cause perforation varies essentially linearly with thickness of the sheathing material for both plywood and OSB. This suggests, at least for this type of missile and common sheathing materials, that a desired target penetration resistance (ability to resist a certain impact momentum) can be achieved by simply adding up the contributions of the various layers of sheathing. For example, in Figure 1, sheathing with a 30/32-inch thickness represents two layers of 15/32-inch material.
