MultiScale Mecahnics of Solids Group
In Dr. Berinskii's group, we use continuous and discrete methods to investigate the mechanical properties of materials and structures. Continuum representation of material is widely accepted in the mechanics of solids. However, at the micro and nanoscale, the microstructure plays a crucial role and cannot be ignored. At these scales, the models representing a discrete microstructure of the material must be considered.
We study a connection between the microstructure and macroscopic mechanical behavior by means of analytical and computational analysis. We effectively solve the quasistatic and dynamical problems involving homogenization, fracture, large deformations, mechanical instabilities, and time-dependent behavior. Our theoretical results are applied to modeling and simulation of low-dimensional nanostructures, architected materials and structures, composite materials, biomaterials and MEMS.
In this work, we propose the unique method for coarse-grained modeling of crystals. The grains are chosen as assemblages of the atoms in the original crystal lattice. The method allows incorporating the grains’ elasticity so that the overall strain uniformly distributes in the lattice to avoid the unexpected stress concentrations in the bonds between the grains.
Dr. Igor Berinskii graduated from St. Petersburg Polytechnic University (SPbSPU) in Russia. He obtained his master's degree at the Department of Mechanics and Control Processes in 2007. In 2010 he got the Candidate of Sciences degree (Equiv. to Ph.D.) in Solid Mechanics from the Institute for Problems in Mechanical Engineering of Russian Academy of Sciences (IPME RAS). In 2012, he got the postdoc position in Nano-Science and Nano-Engineering Group at Cardiff University, UK. After return to Russia in 2013, he served as a lecturer at SPbSPU and a researcher at IPME RAS.
In 2015 Dr. Berinskii moved to Israel to join Tel Aviv University as a visiting lecturer. Since 2019 he holds a tenure-track senior lecturer position and leads the Multiscale Mechanics of Solids Research Group. He investigates a connection between the microstructure and macroscopic mechanical behavior of materials and structures by means of analytical and computational analysis. He aims to explain existing unusual mechanical properties and to predict new outstanding features to be used in engineering applications.
