Towards a universal master curve in magnetorheology

Smart Materials and Structures, 2017
We demonstrate that inverse ferrofluids behave as model magnetorheological fluids. A universal master curve is proposed, using a reduced Mason number, under the frame of a structural viscosity model where the magnetic field strength dependence is solely contained in the Mason number and the particle concentration is solely contained in the critical ...

A Master Thrust‐Curve for Airscrews

Aircraft Engineering and Aerospace Technology, 1944
THOSE engaged on airscrew work are constantly making use of the tables of experimental values of kT and kQ for different values of J given in R.M. 1673. In using these tables it is usually necessary to extrapolate. It is the object of this article to show that, where we have strict grounds for comparison, we can construct a single thrust curve, which ...

Objective comparison of the Unified Curve and Master Curve methods

International Journal of Pressure Vessels and Piping, 2014
The Unified Curve and the Master Curve are two popular cleavage fracture toughness assessment engineering methods. The methods are very similar. They basically differ only in the assumed fracture toughness temperature dependence. The standard Master Curve approximates the temperature dependence as being fixed, whereas the Unified Curve assumes that the

Master curve approach to polymer crystallization kinetics

Polymer Engineering & Science, 1995
AbstractNonisothermal crystallization kinetic data obtained from differential scanning calorimetry (DSC) for a poly(ethylene terephthalate) are corrected for the effects of temperature lag between the DSC sample and furnace using the method of Eder and Janeschitz‐Kriegl which is based on experimental data alone without resort to any kinetic model.

Constructions of master curves and master surfaces starting with experimental data

2007
Starting with the theoretical considerations of our previous papers [1,3], some practical aspects concerning the shift procedures of rheological data are analysed. The latter can be used for the construction of both isotherm and isochrone master curves as well as of master surfaces, with the condition of experimental verification of the validity of the

Fracture Toughness Master Curve of bcc Steels

2012
The Master Curve methodology has been developed as an advanced, direct technique for characterizing the fracture toughness of ferritic structural steels. The application of the methodology has increased during the last decade and spread worldwide extending beyond the initial applications associated with nuclear power plant surveillance and integrity ...

Master Curve for the Discrete-Element Method

Industrial & Engineering Chemistry Research, 2007
The discrete-element method (DEM) is a numerical model consisting of the fundamental laws of motion and a suitable force-displacement model, such as the linear spring-and-dashpot model, as closure. The damping coefficient found in the latter is related to the phenomenological concept of coefficient of restitution of solid particles.

Master Curve analysis of potentially inhomogeneous materials

Engineering Fracture Mechanics, 2012
Abstract The Master Curve methodology is now widely used for ensuring the integrity of ferritic steel structures against brittle fracture. The methodology has been recently extended to the treatment of macroscopically inhomogeneous materials through bimodal and multimodal approaches. This can be of practical importance in many applications.
