Forming Limit Diagrams are useful tools for evaluation of formability in the sheet metals. In this paper the effects of yield criteria on predictions of the right and left-hand sides of forming limit diagrams (FLDs) are investigated. In prediction of FLD, Hosford 1979, “Karafillis-Boyce” (K-B) and BBC2000 anisotropy yield functions have been applied. Whereas the prediction of FLD is based on th...

Fullerene C60 films deposited by sublimation were irradiated with Kr-F laser in a wide fluence interval from 15 to 40 mJ/cm2. In situ photoacoustic analysis was applied to study the phase transformation during the irradiation. The results obtained were discussed in conjunction with atomic force microscopy (AFM) and Raman spectroscopy data. It was found that for a irradiation fluence interval fr...

In this paper, we have investigated the effect of third invariant stress deviator on formation necking instabilities in isotropic metallic plates subjected to plane strain tension. For that purpose, performed finite element calculations and linear stability analysis for initial equivalent rates ranging from $$10^{-4}\,\text {s}^{-1}$$ $$8 \cdot 10^{4}\,\text . The plastic behavior material has ...

VLBI observations at 5 GHz have revealed that supernova 1979C, in the galaxy M100 in the Virgo cluster, has shell structure. The shell is approximately circular with the 50% contour deviating from a circle by an rms of no more than 8% of the radius. The brightness distribution along the ridge may vary. The position of the center of the shell is at R.A.=12 h 22 m 58. s 66758 and decl.=15 • 47 ′ ...

This work established strain-based forming limit diagrams (FLDs) for DP600 steel sheets by means of experimental investigation and theoretical prediction. The results showed that compared to the curve (FLC), predicted Keeler equation, FLCs Hill’79 yield criterion, or Logan-Hosford were more suitable predicting sheets. Solutions from analytical methods FLD, based on combining uniaxial tensile te...
