Does anyone, engineer or otherwise, know of a diagram available on the internet of the stress distribution in a bicyle frame during certain conditions (ie. climbing, coasting, sprinting etc.). Thanks in advance.
it's not really what you're looking for....Andreas_Illesch

YEARS ago, Bicycling did an article.brider

Way back when the magazine had some CONTENT, they stress-guaged a frame and put it through its paces. If memory serves, they found that the down tube was the highest stressed member. They had some cool color-coded pictures. Maybe some out there knows where the article can be found.
Take a course on FEA!Alexx

When I was in school, we all took this course called "Advanced Computational Techniques", which was a 4-credit class, and required that you had already had your classes in Materials, Statics, Dynamics, and Calculus already completed. It was not an easy course, either. A full FEA workup on just one frame would likely keep a single engineer busy in a lab for an entire week. If you'd care to pay for a full analysis on a single frame, ship me the frame, and about $4k, and I'll do it for you.
