Abstract
The mechanical behavior and properties of particle beds relevant to fusion ceramic breeder blanket designs are
addressed through a combination of experimental and analytical studies. A series of uniaxial compression tests are
performed in a INSTRON hydraulic-press test facility in which compressive loads are applied to Li2ZrO3 and
aluminum packed beds. The experimental data shows that the mechanical properties such as the bed effective
modulus are stress dependent and consistent with the analytical model predictions. Nevertheless, the experimental
data shows that the bed effective modulus is approximately two orders of magnitude lower than that of the solid
material. 1998 Elsevier Science S.A. All rights reserved.
1. Introduction
From a structural viewpoint, particle beds are
composed of mutually contacting solid particles,
or structural units. The existence of the contacts
restrict the freedom of motion of the individual
particles, and thus, conditions the strength and
the rigidity of the bed. The mechanical properties
