TOPOLOGICAL CLASSIFICATION OF DEFECTS
When we topologically classify the defects in ordered media, we consider the character of the fundamental group of the associated order parameter space. To construct those groups, we circumscribe the line defects by circles and the point defects by spheres.
My question is what is done for a surface (possibly infinite) defect, say domain walls. My query primary concerns crystal lattices. I want to characterize the essential defects in solid crystals--for dislocation and interstitial/vacancy, it is straightforward. But what to be done in case of grain/phase boundary?
PhD Position available in Computational Multiscale Multiphase Biomechanics at the University of Colorado at Boulder
I am currently seeking a PhD student to pursue a research project on computational multiscale multiphase biomechanics within the Engineering Science PhD program in the Department of Civil, Environmental, and Architectural Engineering at the University of Colorado at Boulder.
Fractography Analysis Using 3D Profilometry
Fractography is the study of features examined on fracture surfaces and has historically been investigated via Microscope or SEM. Microscope being used for macro scale analysis and SEM particularly when it is the nano or microstructure that is vital to the analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope clearly has its limitations and the SEM in most cases, other than atomic level analysis, is unpractical for fracture surface measurement and lacks broad use.
Nanoindentation Fracture Toughness
The ability of a material to resist cracking, or fracture, has been vital to the studies of fracture mechanics. Until recently the study of fracture toughness has been analyzed at a macro range using powerful instrumentation applied to large samples.
Group Leader or Senior Post Doctorate position in Mechanism-Based Modeling and Simulation
INM – Leibniz Institute for New Materials, Saarbrücken, is a basic and applied research institute in transition to new scientific fields. It has approximately 180 employees, excellent research equipment, and is well supported by public and third-party funding. Its traditional focus is chemical nanotechnology, where the institute holds key patents and has close international links to industry. Under new leadership, this focus is now expanding to include promising novel aspects of materials science, physics and biology.
