About Florin Bobaru
Ever wondered why does glass break in such complex patterns, fragments and chips? Or how does corrosion of a few bolts and plates bring an entire bridge down? Our research group works on computational models that answer such questions and explain the behavior observed experimentally in some of the most challenging problems that have puzzled researchers for decades. We use these models for solving problems that deal with heat and mass diffusion, dynamic fracture, and fragmentation. Recent focus is on: peridynamics for impact fracture in glass, glassy-polymers, polycrystalline ceramics, and fiber-reinforced composites; fracture in concrete induced by corrosion; corrosion damage and Stress Corrosion Cracking; dynamics of granular materials and their interaction with elastic media, multidisciplinary optimization, inverse problems, and multiscale and multiphysics methods.
Damage, corrosion, and fracture with peridynamics
The peridynamic theory is a novel reformulation of the classical continuum mechanics which allows one to model fracture, damage, fragmentation in a natural way. In peridynamics, cracks are part of the solution, not part of the problem. We have used such models to explain the role Van der Waals forces play in the deformation and damage behavior of nanofiber networks, to explain the growth of cracks and fragmentation evolution in glass plates, to model trans- and intergranular fracture in polycrystalline ceramics, to discover strain-rate effects in the failure of fiber-reinforced composites, and to simulate the growth of subsurface damage in corrosion. This research is being funded by NSF, AFOSR through a MURI project, by ONR, by NAVAIR, by ARO and ARL. Recent past funding includes grants from Boeing Co, Sandia National Laboratories, Callahan Innovation (New Zealand), NASA.
Dynamics of Granular Materials interacting with vibrating plates
Granular materials are one of the most puzzling material systems. The models we proposed, simulate the dynamic interaction between a layer of granular material and an elastic vibrating plate to provide us with a deeper understanding of the fascinating dynamic behavior of granular materials. Think of a land- or rock-slide and imagine the possibility of predicting their behavior under their interaction with the elastic soil support.
Optimization of material composition
Is it possible to find the "best" composition of a multi-component material (such as a composite or a functionally graded material - FGM) that maximizes its strength or stiffness, and reduces its mass? Our results on optimal material design of FGMs show new possible architectures that minimize the chance of failure due to thermal and mechanical stresses.
Optimal shape design
What is the best shape of a cooling thermal fin? Our novel algorithms compute optimal shape of systems when there are large shape changes between the initial guess and the final optimal design. Our meshfree approach leads to interesting solutions that mimic naturally occurring systems like the plates on the back of a stegosaurus dinosaur, or the extended surfaces on the inner side of the intestine (intestinal villi).
