Prof. Cazacu's main research interests lie in theoretical and computational solid mechanics with focus on multi-scale modeling of dissipative mechanisms in engineering materials for both quasi-static and dynamic regimes.
Prof. Cazacu's key
expertise is in modeling plastic anisotropy . She has
developed a methodology within the framework of the theory of
representation of tensor functions that allows to extend any
given isotropic yield criterion such as to account for
particular material's symmetries. For polycrystalline metallic
materials with hexagonal crystal structure, Prof. Cazacu and
collaborators have developed the only existing analytical
macroscopic level elastic/plastic models that account for both
anisotropy and tension-compression asymmetry in
In the field of ductile damage, recently Prof. Cazacu and her UF-REEF collaborators demonstrated that the presence of voids induces dependence on all invariants, the noteworthy result being the key role played by the plastic flow of the matrix on the dilatational response. Furthermore, open problems posed by Rice and Tracey (1969) concerning the rate of damage in a porous solids were solved.
