Effective Yield Strength for Material Powder Consolidated at Stage II Compaction ()
ABSTRACT
This work
is concerned with the estimation from the outside of effective yield strength
for the stage II consolidated material package of axisymmetric solid particles.
Once an appropriate simple representative axisymmetric unit cell is chosen, the
kinematical approach of the yield design homogenization method is used in order
to obtain external estimates which has been found depending on the loading
history (isostatic and closed die compactions) as well as on the relative
density of the material powder. For comparison purpose, finite element
simulations that describe the behavior of spherical elastic plastic particles
uniformly distributed inside the material powder are carried out.
