I am considering purchasing a raised floor to place couple of digital copiers (Xerox Docu Tech). The floor is a concrete floor made by Tech Crete. The floor manufacturer says the floor can support up to 450 lb/sq-ft. The uniform load for each machine is approximately 90 lb/sq ft. Therefore...
I want to do some stress analysis on a powder metal part. Can I just run the analysis the way I would for a machined part and just substitute the modulus of elasticity and poisson's ratio of the powder metal material?
Is it correct to welded connections using coincident nodes or rigid links? How reliable are the stresses at the welded connection when using coincident nodes or rigid links? Is there one technique preferred over the other?
