I'm not very proficient at aero- or fluidynamics or stress calculations, but I want to know how to calculate the stress on parts of a given rocket, given the height(or air density), orientation and velocity vector of said rocket.
For example one could ask: 'Is the stage connector which can sustain this much stress capable of flying through max Q?' where one has the data on how much stress it can endure but not on how much it will experience.
Edit 2: Firstly, what forces do act on a rocket and parts of that rocket? Aerodynamic drag, gravity, acceleration from the thrusters, obviously, but which are important in this calculation? And secondly, while I may be able to google the formulas for all of these forces and more, how do I 'convert' from force to mechanical stress? This is the real problem, I think.
I do not need the 100% perfect solution, an approximation suffices.
Thanks in advance, JAG
Edit: maybe a simple usecase would be helpful: given a very oversimplified rocket consisting of four parts (engine, tank, separator and payload with fairing) of known stress endurance (although I do not know how to express this - oopsy) the mechanical stress would be different on every part when taking a trajectory, where the rocket is not pointing in the direction of travel at this point than flying straight up. How would i go about calculating this stress, both drag-induced and otherwise for every of the four parts and compare it to the allowed values?
Meta: Firstly, to give some context: This is research for building a game (actually a mod). So I need this to calculate whether a rocket would explode or tear apart at every point in time. Secondly, should I delete obsolete information which got updated by an edit or keep everything for reference? It kinda gets too long and messy...
