Nanocomposite structure, consisting of hard mineral and soft protein, is the elementary building block of biological materials, where the mineral crystals are arranged in a staggered manner in protein matrix. This special alignment of mineral is supposed to be crucial to the structural stability of the biological materials under compressive load, but the underlying mechanism is not yet clear.

JMPS paper: "Some basic questions o mechanosensing in cell–substrate interaction"

In this paper, a mechanical model of cell-substrate interaction is constructed and discovers the mechanisms of cell sensing  compliance, thinckness and distance. If you are interested, pls see details in the paper.

Postdoctoral positions in Computational Materials

Submitted by pkroll on

A postdoctoral positions in Computational Materials is available in the group of Peter Kroll in the Department of Chemistry and Biochemistry at UT Arlington, Arlington, TX. The project focuses on boron nitride, its conversion from "soft" hexagonal to "hard" cubic boron nitride, structural developments during sintering, and mechanical properties. Applicants will have a strong record in solid-state materials simulation and the demonstrated ability to work independently and drive a project.

Extreme Computing

Extreme Mechanics
high-performance computing
large-scale multiscale modeling and simulation

There have been several discussions on "Extreme Mechanics" in recent weeks and I would like to extend this topic to "Extreme Computing". As we develop materials that are more complex, hierarchical and are spanning multiple spatial scales, we will need computational tools that can describe them well. Fluid dynamics community has long time ago embraced large-scale computing of conservation laws of mass, momentum and energy. In mechanics of materials, large-scale computing is still in infancy.

Recovery of electrical resistance in copper films on PET subjected to a tensile strain

For flexible electronics applications it is important to understand the behavior of electrical resistance of metal films on polymer substrates under applied tensile strain. Although the growth of resistance during tensile loading was investigated in a number of research papers, the recovery of resistance during unloading remains virtually unexplored. In this paper, substantial recovery (decrease) of electrical resistance during and after unloading is demonstrated for copper films on polyethylene terephthalate (PET) substrates subjected to a tensile strain with different peak values.
