Dynamic Mechanical Properties of Maxillofacial Materials [PDF]

Journal of Dental Research, 1975
Six maxillofacial materials were evaluated by determining their dynamic properties with use of a Goodyear Vibrotester. The dynamic modulus, internal friction, and dynamic resilience were measured for all materials over a temperature range of -15 to 37 C. The dynamic modulus ranged from 11.1 to 124.8 kg/cm2 and the dynamic resilience varied from 1.1 to

Design and manufacture of testing measurement and evaluation device for dynamic property of metallic interfaces

Nihon Kikai Gakkai ronbunshu, 2015
Metallic interfaces in mechanical structures cause dynamic damping property. It is very effective to apply this good damping property to engine power plant in order to reduce noise and vibration, however, it is difficult to use dynamic damping property ...

Energy Levels of "Hydrogen Atom" in Discrete Time Dynamics [PDF]

, 2006
We analyze dynamical consequences of a conjecture that there exists a fundamental (indivisible) quant of time. In particular we study the problem of discrete energy levels of hydrogen atom.

A Novel Design to Eliminate Lüders Band in Medium-Mn Steel and Its Microstructure-Property Relationship

Crystals, 2023
In the current work, we design a novel medium Mn steel with a superior mechanical property and no Lüders band. For industrial applications, a “low Mn addition” chemical composition and two kinds of different annealing processes with various initial ...
