Dynamic plastic necking instabilities for a biaxially pulled plate

Abstract
The growth-rate and the modes of dynamic plastic necking
instabilities for a biaxially pulled plate are calculated
analytically. The material is supposed incompressible and
elastoplastic, and it obeys the Mises yield criterion. The
yield-stress follows the SCG model. The mass and momentum
conservation laws are linearized by supposing that the ground flow
perturbation has low amplitude and high growth-rate. The velocity
perturbation is decomposed into Fourier modes. The results of the
analysis agree with the results of Shenoy and Freund for a
uniaxially pulled plate [1].
