Is torsion applied around an axis "sheer" force? ie the failure mode for cylindrical part being twisted apart. Would that be remedied by a material suited more for elongation or should I aim for the next failure to be a "hard" or brittle break? 8/25/2017 3:44:21 AM |

It's both. Read up on Mohr's Circle.
As far as failure mode, it depends on if it's pure torsion, or if there's a compression/tension load as well...plus I think probably the material and the dimensions of the component. 8/26/2017 6:18:12 PM |

draw a cube for a random section somewhere inside the bolt, then make a free body diagram for that cube 8/26/2017 10:11:21 PM |

also, if your knuckles are exposed, be prepared for a hard break. 8/29/2017 10:00:15 AM |
