When I came to the institute, my collaborator Kay invited me for a dinner in the new town together with his friend Thilo and other guys. The city is wisely divided into two functioning areas, old town and new town. All the ancient buildings like King’s summer palace, women’s church and opera house are in the old town; while the restaurants, bars and other modern buildings are in the new town. Each is in harmony with its environment and cultural atmosphere.

The stress-strain behavior and incipient yield surface of nanoporous single crystal copper are studied by the molecular dynamics (MD) method. The problem is modeled by a periodic unit cell subject to multi-axial loading. The loading induced defect evolution is explored. The incipient yield surfaces are found to be tension-compression asymmetric. For given void volume fraction, apparent size effects in the yield surface are predicted: the smaller behaves stronger.

Dear Researchers,  

I am a research student, "Surface modification of materials" is my research topic. I joined your site to discuss the crack propagation during thin film deposition.

 It seems that within the field of fracture mechanics, some authors use "fracture" to refer to the mechanism of creating new surfaces within a body by breaking the material bonds and reserve the word "crack" for the sharp-tipped discontinuity that results from fracture of a brittle material. But it does not appear that this distinction is followed consistently throughout the literature, and perhaps different research areas within the fracture mechanics field use the two words in different ways.

It may be well known to researchers on ferroelectrics that tetragonal ferroelectric ceramics, such as BaTiO₃, Ti-rich lead titanate zirconate (PZT), are difficult to pole even using a high DC field with long holding time. While the rhombohedral PZT or PZT near the morphotropic phase boundary (MPB) are easy to pole, especially the latter. Why?

The post doctoral fellow will be engaged in research on the mechanics of hydraulic fracturing of rock. The primary aim of this project is to investigate, using a novel approach for experimentation spanning laboratory and field scales, the effect of fracture size on the energy required for fracture extension in rock.
