Fracture is caused by sheet's tensile instability, Hill's totalized instability theories and Swift's diffuse instability theories which based on continuous mechanics are applied to isotropic blank; Marciniak and Kuczynski's theories are applied to orthotropic blank, which introduced thickness imperfections normal to the principal stress and strain direction as a groove pre-existing defects in the material. The stability of each part of blank at each moment is described by numerical method, and the results are shown by computer simulation, thus the fracture in sheet forming can be predicted preciously.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
