Not really. Most graphite fly rods are designed for their deflection characteristics and, since they have such high tensile strength, stress is usually not a factor. Bamboo rods, with their lower tensile strength, are usually designed for stress limits. Don Phillips has a good book on it.

Graphite rods are sensative (very) to cracks and damage. It has been said more rods are broken by weighted streamers than any other cause. You hit the rod, crack the finish, and the rod breaks from the resulting stress concentrations.

You can break most rods by candycaneing them but I think glass and bamboo might be more sensitive to this type of failure than graphite. I have broken two Orvis 2 piece rods this way, (my bad), both of them in the exact same place - right above the ferrule. I suspect a design flaw since there is a section transition there.

Godspeed and good fishing,
