About Sreekar Rayaprolu

I am a computational materials scientist with significant experience in modeling the microstructural evolution of metals under irradiation using phase-field models. Furthermore, I consider myself a theoretician who loves developing new mathematical models that capture the multi-physics governing mechanisms underlying microstructural evolution. In addition, I am also experienced in conducting atomistic-scale studies through Molecular Dynamics simulations. I recently developed a quantitative phase-field model for void evolution in single-crystalline, irradiated metals that, for the first time, captures the asymmetry in the defect reaction rate at the void surface through a two-mobility Allen-Cahn equation. I also accurately pinpointed the annihilation rate of the defect at the void surface through a modified Cahn-Hilliard equation. Moreover, I have extended the sharp-interface theory for void evolution in single-crystalline irradiated metals by coupling it with the finite-deformation theory, accounting for interfacial stresses, anisotropic interfacial energy, and defect eigenstrain through a multiplicative decomposition of the deformation gradient. To know more about my research experience and publications that have been published or are soon to be submitted, kindly check out my CV.I see myself in the future working on problems spanning multiple spatial and temporal scales related to microstructural evolution in single- and multi-component systems governed by multiphysics effects, Fracture Mechanics, Heat Transport, Continuum Mechanics, and Atomistic modeling.
