But everything but the easiest case (a unidirectional c.f. rod rod under straight tension) quickly becomes mathematically challenging, including tensor multiplication etc.. and to set up the equation you will need some skills in static/dynamic mechanics. Additionally some of the mechanical propertys you need are very hard to get/ have to be determined by experiments.

But maybe there are more rough ways to calculate the strength ? For example, I would be interested to make a support stand. Is it possible to evaluate the strength only experimentally?

Unfortunately this is nothing you can learn within an hour internetting. This usually takes at least 3 semesters at the university. Especially if you really want to be shure you are doing it right. You could make smaller models and get results for a full scale model by experiment. But neither length not thickness are acting linear when it comes to bending, so again you need the mechanical understanding to get anything helpfull out of experiments.
