  • he explains that loss of the fluid-attaining proteoglycans (Pg) inside the cartilage collagen network is the earliest indicator of osteoarthritis. loss of Pgs increases the water permeability of cartilage and decreases the tissue stiffness, leading researchers to propose proteoglycans as an important marker for the early detection of osteoarthritis. To precisely determine the Pg content in cartilage, lu is investigating a mechanical testing approach with the aid of advanced theoretical modeling.

  • In this paper, new simulation techniques are described to determine instability-free configurations, making it possible to guarantee that the final workpiece profile is round. With this information and taking into account other process restrictions, like system static stiffness and workpiece tolerance, the optimal grinding cycle is designed. These results have been implemented into an intelligent tool to assist the application of this research in industrial environments.
