  Study on high-speed grinding mechanisms for quality and …

  2013102 · This paper focuses on the mechanism of high-speed grinding to achieve quality and efficiency for ceramics. The criterion of the brittle–ductile removal transition of ceramics is calculated and analyzed. The effects of the wheel velocity on the specific grinding forces, energy, and specific material removal rates were investigated. The …

  3D printing of extremely viscous materials using ultrasonic vibrations ...

  201881 · Abstract Heterogeneous materials used in biomedical, structural and electronics applications contain a high fraction of solids (>60 vol.%) and exhibit extremely high viscosities (μ > 1000 Pa s), which hinders their 3D printing using existing technologies. This study shows that inducing high-amplitude ultrasonic vibrations within a nozzle …

  LUBRICANTS FOR HIGH-PERFORMANCE GRINDING OPERATIONS

  For HEDG-grinding of hard materials with high cutting speed rates and high axial infeed rates, MKU-Chemie recommends therefore a special additive doped grinding oil which lowers friction in the contact zone and lead in addition to a stable lubricant film in the contact zone, generated by a medium viscous oil.

  Viscoelasticity | SpringerLink

  202011 · Definition A wide group of materials, such as metals at high temperatures, polymeric materials, biopolymers, or biological tissues, exhibits gradual deformation and subsequent recovery in time. The response of those materials is dependent upon the stress-strain rate and the temperature itself. This temperature and time-dependent material …

  On a mixture of an MGT viscous material and an elastic solid

  202217 · A lot of attention has been paid recently to the study of mixtures and also to the Moore–Gibson–Thompson (MGT) type equations or systems. In fact, the MGT proposition can be used to describe viscoelastic materials. In this paper, we analyze a problem involving a mixture composed by a MGT viscoelastic type material and an elastic …

  Glue-assisted grinding exfoliation of large-size 2D materials …

  2021121 · Abstract Two-dimensional (2D) materials have many promising applications, but their scalable production remains challenging. Herein, we develop a glue-assisted grinding exfoliation (GAGE) method in which the adhesive polymer acts as a glue to massively produce 2D materials with large lateral sizes, high quality, and high yield.
