When I first started in a development department, measuring parts was done with simple tools like calipers, micrometers, dynamometers… new equipment started to appear resorting to 3D measurements automatic measurements with a computer with a ball pointer. Drawings were not measurement friendly making it difficult to measure according to new technologies. Today’s approach take seriously GDT and combining it with CT scans (3D scanner) a new approach is starting to grow resorting to model based definitions. Since all the information necessary for measurement is in a model when a CT scan is performed one can imideatly discover part variation and perform analysis on the intended planes with no miss communication.
Finally I got time to mesh and solve my imaginary problem. I will not dive into meshing since it is a chapter on its own. I used a tetrahedron mesh as standard as it gets. The work flow is simple; get a CAD model, get material data, mesh it, add supports and loads and finally get some results, either by stresses or displacements.
My results for a small load of 1.2Kg shows that the T tube element will suffer most when we sit on it. I would say that if it breaks it will be there. Ok this case is more then evident since the only thing holding my weight is this connection.
