    Forming operations cannot be easily performed on brittle materials. For example, brittle material cannot be drawn into wire. Ductile materials show longer life when subjected to fatigue loading. Brittle materials fail faster when subjected to fatigue loading. Examples of ductile material: Mild steel; Aluminum; Copper; Rubber; Most plastics

  • ductile regime grinding of brittle materials experimental

    Ductile-regime grinding is a new technology made possible by the use of real-time control and precision engineering in the grinding process. By ensuring that the abrasive grinding forces do not exceed a threshold value, it is possible to grind materials that are normally considered "brittle" in such a way that the material removal takes place through plastic deformation rather than …

    This indicates that the transition from ductile deformation to the brittle fracture removal mode must be considered when modelling the grinding force for ceramics. Therefore, Wu et al. extended Hecker’s model and predicted the grinding force for brittle materials considering the co-existence of ductility of brittleness. In this model, the surface and subsurface damage was quantitative …
