Jd. Guerin et al., ANALYTICAL AND FINITE-ELEMENT ANALYSIS OF IN-SITU SOLIDIFIED SPECIMENUPSETTING, Journal of materials processing technology, 49(3-4), 1995, pp. 399-423
The behaviour of solidified steel in the continuous casting process is
determined by means of a laboratory-scale upsetting test of specimens
that are obtained by fusion and in-situ solidification in the test ma
chine. From the curves of upsetting load-cylinder height decrease and
the initial and final specimen dimensions, the stress-strain-strain ra
te relationships and the related equatorial stress-strain paths are ca
lculated using an analytical model, the performance of which is estima
ted by comparing the results with those given by non-linear finite-ele
ment models. Reference experiments are achieved on in-situ solidified
A 283 steel cylinders at 1050 degrees C; stress-strain-strain rate rel
ationships, equatorial strain and stress paths being determined. The a
nalytical results give rather good estimates, especially for strain an
d strain rate.
