The effective modulus interpretation of the strength-differential effect in ferrous alloys

Scripta Metallurgica, 1972
Abstract The S-D effect in steels is satisfactorily explained by the influence of the effective modulus on the internal stress. The difference in effective modulus in compression and in tension arises from the nonlinear elastic stress strain relations at high elastic strains.

Comments on “The strength differential and bauschinger effects in SiC-Al composites”

Materials Science and Engineering: A, 1989
We discuss here the interpretation given by Arsenault and Wu of the Bauschinger effect for metal matrix composites and explain why their usage of the Bauschinger strain relation derived by Pedersen et al. for pure copper is misconceived. We then further analyse the data to highlight the importance of relaxation.

Modeling of Strength Differential Effects in HCP Sheet Materials

Volume 2: Processing, 2014
A simple approach is proposed to employ symmetric yield functions for modeling the tension-compression asymmetry commonly observed in hcp materials. In this work, the strength differential (SD) effect is modeled by choosing separate symmetric plane stress Barlat Yld 2000 yield functions for the tension i.e., in the first quadrant of principal stress ...

The strength differential and Bauschinger effects in SiCAl composites

Materials Science and Engineering, 1987
Abstract An investigation was undertaken to determine the effect of an average elastic residual stress on the strength differential and the Bauschinger effects in SiCAl alloy composites. It was found that the compressive yield stress on the omposites was greater than the tensile yield stress for whisker- and platelet-reinforced composites but, for ...

Effect of hydrostatic stress on the strength differential effect in low-carbon steel sheet

International Journal of Material Forming, 2022
The effect of hydrostatic stress on the strength differential effect (SDE) in a 0.8-mm-thick low-carbon steel sheet is experimentally investigated. The in-plane compressive stress-strain curve is approximately 10% higher than the uniaxial tensile stress-strain curve at a strain of 0.15, confirming that the test sample exhibited the SDE.

The effect of a zirconium strength differential on cladding collapse predictions

Journal of Nuclear Materials, 1975
Abstract An investigation was made into the occurrence of a strength differential in the Zircaloy cladding of LWR fuels, and into the effect such a strength differential can have on the analytical predictions of cladding creep collapse during fuel densification. The strength differential, or SD, refers to the difference in the compressive and tensile

Temperature dependence of the strength-differential effect in hardened steels

Metallurgical transactions, 1974
The strength differential (SD) has been measured as a function of temperature in a fully hardened 0.2C, 6 Ni steel, quenched and then tempered at 250°C. It is found appropriate to express the results in terms of the intercept flow stresses as extrapolated back to zero plastic strain.

Differential effects of list strength on recollection and familiarity.

Journal of Experimental Psychology: Learning, Memory, and Cognition, 2002
Numerous studies have found a null list strength effect (LSE) for recognition sensitivity: Strengthening memory traces associated with some studied items does not impair recognition of nonstrengthened studied items. In Experiment 1, the author found a LSE using receiver operating characteristic-based measures of recognition sensitivity.

Effect of martensite morphology on the strength differential effect in dual phase steels

Scripta Metallurgica, 1984
Abstract The formation of elongated martensite particles leaves residual axial tensile stresses in much of the ferrite. In the hydrostatic pressure tests, all conducted in tension, this residual stress does not affect the pressure dependence of the flow stress. Hence the mechanical responses is not unusual.

Differential effects of whole body vibration durations on knee extensor strength

Journal of Science and Medicine in Sport, 2009
The effectiveness and optimality of whole body vibration (WBV) duration on muscular strength is yet to be determined. Hence the aim of this study was to investigate the effects of three different durations of continuous WBV exposure on isometric right knee extensor strength measured pre and post exposure.
