Stresses in a conical tube under sudden loading

M. A. Zadoyan
Institute of Mechanics, Armenian National Academy of Sciences, Erevan 375019


The paper considers a thick-walled long
conical tube from an ideal plastic
material whose inner surface is suddenly
subjected to time-constant, uniformly
distributed pressure or is given a
velocity. An ideal-plastic zone
propagates from the inner conical
surface. It is assumed that the material
of the tube is incompressible in both
the elastic and plastic zones. The
plastic material obeys the
Houber<!ndash!>Mises plasticity
condition. P. 140-146
