Material damage induced by corrosion can trigger sudden failure of structures by introducing pits that act as stress concentration points from which cracks initiate and propagate catastrophically. Many materials are also susceptible to Stress Corrosion Cracking (SCC) in which changes introduced in the material by corrosion processes dramatically reduce its fracture toughness. This talk will present our efforts on predicting the evolution of corrosion damage, pitting corrosion, and SCC, to better understand failure of materials in corrosive environments. The new models we introduced are of peridynamic type (nonlocal models) that allow for a consistent treatment of damage and cracks in a variety of forms in which they are present in corrosion processes. I will cover a recent model we introduced that is capable of simulating the passivation, salt-film formation, and the autonomous formation of lacy covers in pitting corrosion. The computational results under potentiostatic conditions are in excellent agreement with experiments in both time-scale and length-scale. The model is also used to investigate the effect stresses have on corrosion rates, and SCC. I will give a brief account on why peridynamic modeling of fracture, damage, fragmentation is useful.

About the Speaker

Prof. Bobaru obtained his Ph.D. in Theoretical and Applied Mechanics from Cornell University in 2001. He holds B.S. (1995) and M.S. (1997) degrees in Mathematics and Mechanics of Solids from University of Bucharest. He joined University of Nebraska-Lincoln as Assistant Professor in 2001, where he has been Full Professor of Mechanical and Materials Engineering since 2013. Prof. Bobaru has had Visiting Scholar appointments at Sandia National Laboratories (2002-2005, 2009), at Cambridge University (2008), at California Institute of Technology (2011), at University of Padova (2015), and at University of Texas at Austin (2015). He has published extensively on peridynamic modeling of dynamic fracture and failure and he introduced peridynamic models for heat flow in bodies with evolving discontinuities and corrosion damage. Other publications include shape and material optimization, and dynamics of granular materials. He is the main editor of the recently published “Handbook of Peridynamic Modeling”.

Physics Colloquium- David Reitz @ 1080 Physics Research Building
Feb 28 @ 3:45 pm – 4:45 pm

Colloquium – David Reitz (Caltech LIGO) Black Holes’ Last Tango: LIGO and the Dawn of Gravitational Wave Astronomy

Tuesday, February 28, 2017 – 4:00pm to 5:00pm
1080 Physics Research Building – Smith Seminar Room – reception at 3:45pm in the Atrium

The first direct detections of gravitational waves in late 2015 were made possible by a forty year experimental campaign to design, build, and operate LIGO, the Laser Interferometer Gravitational-wave Observatory.  In this colloquium, I’ll cover gravitational waves and what makes them so difficult to detect and at the same time such powerful and unique probes of the universe. I’ll also give a flavor of the somewhat complicated history of how LIGO was conceived and built.  Most of the presentation will focus on the interferometers, the LIGO detections and their astrophysical implications.  Time permitting, I’ll give a preview of where LIGO intends to go in the next decade and beyond.

“Microfluidics for Mapping Epigenomes in the World of Precision Medicine”

Precision medicine requires comprehensive analysis of the molecular drivers of a disease for individual patients and use of the information to devise therapeutic procedures. In the post-genome era, such analysis benefits tremendously from decreasing cost of next-generation sequencing and improvement in big data processing. However, critical technical barrier still exists for establishing genome-wide profiles using tiny amounts of samples extracted from patients and lab animals. In this seminar, I will discuss our efforts on using microfluidics as a versatile platform for profiling epigenomes based on a low number of cells in the context of precision medicine. The epigenome turns on and off genes in a highly dynamic fashion during normal development and diseases, forming another layer of regulation on top of gene sequence. We developed MOWChIP-seq to profile histone modifications using as few as 100 cells (2015 Nature Methods). More recently, we developed microfluidic assays to probe genome-wide DNA methylation. I will discuss our studies of cell-type specific epigenomic landscapes in the context of stem cell differentiation and brain functions using these tools. These new technologies will generate insights into disease processes and help create personalized treatment strategy.

 

Bio:

Dr. Chang Lu is the Fred W. Bull professor of chemical engineering at Virginia Tech. Dr. Lu obtained his B.S. in Chemistry with honors from Peking University in 1998 and PhD in Chemical Engineering from University of Illinois at Urbana-Champaign in 2002. He then spent 2 years as a postdoctoral associate in Applied Physics of Cornell University. His research has been in the general area of developing microfluidic technologies for molecular/cellular manipulation and analysis, with recent focus on profiling epigenomes using tiny amounts of samples. These technologies have been useful for understanding disorders and processes such as cancer, stem cell differentiation, and brain development. Dr. Lu received Wallace Coulter Foundation Early Career Award, NSF CAREER Award, and VT Dean’s award for research excellence among a number of honors.
