Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The effects of microscopic pores, during the historical
deformation on the behavior of ductile
material are experimentally and numerically investigated.
The material used in this study is
constituted from the glass beads which are incorporated
in the polyester resin. During moulding
of these constituents, the pores remain in
the material because of the resin viscosity. The
experimental technique used for the characterization
of the effect of pores is the tensile test.
The constitutive equations of poroelastoplasticity
are developed according to the micromechanical
consideration. The material model developed
by Gurson is extended to this composite
material. The numerical results are obtained
and compared with the experimental ones. |
