| Description |
The design and manufacturing of new engineering materials relies
heavily on the development of adequate models for the description of
the macroscopic behavior of materials with microstructure. These
models have to incorporate the information from a microscale on the
presence of voids or particle/fiber-reinforced structures in materials
and on the mechanisms that determine the behavior under consideration.
Experimentally it is well demonstrated that the hindering of the
dislocation motion by other dislocations, reinforced
micro-particles/fibers or by grain boundaries in alloys cause the
hardening effects, which are observed at the structural scale. The
nucleation and the growth of grain boundary cavities lead to
microcracks developing along a gain boundary and further to failure or
rupture of the material. The primal goal of this project is to derive
the mathematically rigorous description of the macroscopic evolution
of elasto/visco-plastic materials, which are periodically/randomly
voided or reinforced by micro-inclusions of different geometry, during
the deformation in Sobolev spaces with measures. Dependence of the
macroscopic properties of porous or micro-structured materials on the
shape of voids or constituent micro-inclusions, on their
concentration, on their geometric arrangement and on the material
parameters of their constituents must be investigated as well.
