High creep resistance

WebThe main idea of SVC is to map data space to a high-dimensional feature space using a Gaussian kernel function. Next, a sphere with a minimum radius is obtained and the sphere contains most of the mapped data [41,42]. After being mapped back to the data space, the sphere can be separated into several parts, each containing a single cluster ... Web1 de abr. de 2024 · The application of nanocrystalline (NC) materials at high temperatures is challenging due to their poor thermal stability or low creep resistance.

Creep can occur in polymers and metals which are considered viscoelastic materials. When a polymeric material is subjected to an abrupt force, the response can be modeled using the Kelvin–Voigt model. In this model, the material is represented by a Hookean spring and a Newtonian dashpot in parallel. The creep strain is given by the following convolution integral: WebResearchGate
