The teeth of a loaded rotating gear are subject to stresses at the root of the tooth and at the contact surface. If the gear is lubricated, the bending stress is the most important parameter.

How do you create an FEA idealization to perform a nonlinear static analysis using surface contact? In the block-and-ramp problem, a block on a ramp has its weight acting down. Reaction forces ...

Plasma-enabled engineering can create contact-killing, antifouling, and drug-release surfaces. Contact-killing materials destroy microorganisms through the microscopic spikes that puncture ...
