The deformation of round tensile bars subject to dynamic loading is studied numerically using two different plasticity theories: J 2 -flow theory and J 2 -deformation theory. Time development of neck localization is visualized and a comparison of the necking patterns obtained using the two different

Neck localization during high rate extension of round bars is analyzed numerically. An axisymmetric problem formulation is given and the material is described as rate independent and elastic-plastic. The time history of neck development is investigated and effects of geometry and initial thickness i
The waves generated by an obstacle moving with constant velocity U along the axis of an inviscid, incompressible, infinitely conducting fluid with Hall current effects, rotating with an angular velocity D are studied by Lighthill's technique. Three cases arise according as U > A 1, U ~ A 1 or U < A
