I focus on the development and application of advanced numerical methods for analyzing fracture and strain localization phenomena in engineering materials. My research is primarily centered on the peridynamics method, with particular emphasis on its non-ordinary state-based (NOSB) formulation, which enables the direct implementation of constitutive models derived from classical continuum theory.
In parallel, I am developing an approach based on the Cosserat pseudo-continuum theory, which makes it possible to account for the effects of microrotations and material structure through the introduction of an internal characteristic length scale. The integration of Cosserat theory with the peridynamics method enables a more accurate representation of strain localization phenomena, including the formation of shear bands as well as the initiation and propagation of cracks in elasto-plastic materials.
In my work, I combine theoretical modeling with the implementation of original numerical algorithms in MATLAB, along with the validation of results using experimental data (including mechanical tests, microscopic analyses, and nanoindentation measurements).
The goal of my research is to develop tools that allow for more realistic and efficient modeling of complex mechanical phenomena in structural materials, including those produced by additive manufacturing.
