The elbow is a joint, not a bone. Nowhere in an anatomy book will you find a bone called the "elbow", its like a lap, its something that is named but doesn't technically exist, it's where the ulna/radius attach to the humerus.
When you armbar someone, you are hyperextending the elbow joint. That's it. Where each persons weakest link will be different, some people maybe their brachiialdactyl will give out first, maybe the bicep, who knows.
