A cleavage toughness master curve model
Journal of Nuclear Materials, 2000Abstract Development of fusion power will require a fracture toughness database, derived largely from small specimen tests, closely integrated with methods to assess first wall and blanket structural integrities. A master curve-shift (MC–ΔT) method has been proposed as an engineering expedient to treat the effects of structural geometry, irradiation,

An Overview of Master Sintering Curve
Applied Mechanics and Materials, 2012The search for a simple, accurate model to predict the sintering behavior is still a valid challenge facing the particulate materials industry. In spite of the sophistication of the before proposed methods, most models have not yet attained a desirable level of applicability.

Master curve for viscous crack healing
Materials Letters, 2018A novel method to generalize kinetic data of viscous crack healing in glasses is proposed. The method assumes that crack healing progress is proportional to the healing time, t, and indirect proportional to viscosity, n. This way, crack length and crack width data, normalized to the initial crack length and plotted versus t/n, allow to compare crack ...

Master John Perks and his Mechanical Curves
Centaurus, 1963The elusive minor English mathematician John Perks (floruit c. 1700), master of a `hospital' (charity apprentice-school) in Worcestershire and friend of De Moivre and John Colson, is now remembered -- if at all -- for an ingenious elementary quadrature of a circle-lunule [Philos. Trans.

The master curve method: a new concept for brittle fracture
International Journal of Materials and Product Technology, 1999The term fracture toughness usually refers to the linear elastic fracture resistance parameter KIC. In the case of structural steels. The estimation of KIC is limited to the lower shelf of toughness or requires extremely large specimens. This specimen size requirement has been one major obstacle for applying fracture mechanics in structural integrity ...

Master Curve analysis of inhomogeneous ferritic steels
Engineering Fracture Mechanics, 2004The basic Master Curve (MC) method for analysis of brittle fracture test results is intended for macroscopically homogeneous ferritic steels only. In reality, the steels in question are seldom fully macroscopically homogeneous. The materials' toughness may depend on the specimen location in the sample. Inhomogeneity may be deterministic or random (or a

Flaw Evaluations Using Master Curve Methodology
Volume 6: Materials and Fabrication, 2007The Master Curve (MC) reference temperature, T0, characterizes the fracture performance of pressure vessel steels in the ductile-brittle transition region. An MC-based flaw-evaluation analysis procedure that accounts for the variations of stress intensity factor, temperature, constraint, and material conditions is presented.

Master Transduction Curve for Field-Structured Chemiresistor Calibration
Analytical Chemistry, 2010Chemiresistors are gas sensors for volatile organic compounds that are composed of conducting particle networks in a polymer matrix. In the presence of an analyte that is compatible with the polymer phase, the sensor conductance decreases as the analyte is absorbed, eventually reaching a steady-state value that is a measure of the analyte's ...

Master curves for some amorphous polymers
Journal of Applied Polymer Science, 1964AbstractMaster curves for polystyrene, poly(methyl acrylate), and poly(methyl methacrylate) in stress relaxation are reported. The method used to obtain a wide range in modulus is to combine torsional creep data for high modulus regions with direct stress relaxation data for low moduli.

Master Curve of Irradiated JRQ Material
2004One of the key issues concerning the structural integrity of a reactor pressure vessel (RPV) is the effect of neutron irradiation on fracture toughness. To assure the structural integrity of the RPV it is necessary to adjust the pressure-temperature operational limits. These limits depend on the fracture toughness of the RPV material, which is affected
