Not designed for stress

Having been trained to do non-destructive testing on military aircraft (looking for stress cracks and discontinuities in aircract structures per manufacturers manual) I can easily see how a bike frame can crack if stress is applied to a part of it, that the frame was not designed or stress tested for by the manufacturer. But how does a rider rest their leg on the frame at a stop? I've 9,000 miles of loaded touring, and 2 years as bike messenger, and I've had my leg next to the top tube, but never ON the top tube, at a stop.
