The forming limit diagram (FLD) is used in sheet metal forming analysis to determine how
close the sheet metal is to tearing when it is formed into a product shape in a stamping process…

BACKGROUND: Fresh frozen plasma (FFP) has been used as a treatment option for patients
with hereditary angioedema (HAE) because it contains C1 esterase inhibitor, and alternate …

… Since the authors only reported the parameters for a power law "t to the stress}strain relation,
the parameters for the saturation law were calculated from a "t to data over the applicable …

… The equations used in the translation from strain to stress are described by Stoughton 9 and
will not be repeated in this report. In the current work, additional analyses of the pair of error …

An improved model of material behavior is proposed that shows good agreement with
experimental data for both yield and plastic strain ratios in uniaxial, equi-biaxial, and plane-strain …

… Then in comparison to isotropic hardening, we will continue to use the compliance factor to
define the work hardening variable in the Stoughton and Yoon version of non-AFR, and finally…

… 1 shows an FLC computed for a 2008-T 4 alloy sheet sample using the MK model for several
yield criteria. The inputs for the MK model are a yield function, a reference hardening curve …

… p and d σ ̂ y σ ij d t ⩾0. As it will be shown, it does not matter if we define the neutral loading
condition(16) σ ̂ y σ ij = σ ̄ Y ε ̄ p and d σ ̂ y σ ij d t =0 as elastic or plastic deformation. …

In the present study, the initial and subsequent yield surfaces in Al 6061-T6511, based on
10με deviation from linearity definition of yield, are presented. The subsequent yield surfaces …

Many practitioners of the metal forming community remain faithful to the idea that strain metrics
are useful for formability assessment, while many others who are aware of the limitations …
