Analyzing one-bolt joints with FEA would usually call for modeling a small assembly, friction, and contact. And unless the design is for a limited life, the complex effort is overkill. Boltcalc software may be a better way.
Getting a department or company's first FEA program up and running takes more than just learning the software. It calls for training users and establishing a process that lets designers get maximum benefit from the software.
Most products are built to specifications that include some measure of reliability. In the design stage, FEA does a good job of pinpointing the weak spots in parts and assemblies. But the real test comes from field trials when a select set of...
Researchers at the University of Maryland use laser-doppler anemometry to measure velocities of a rotor and material in a mixing vat, and then verify results with a CFD (computational fluid-dynamics) program.
