Mechanics of Crystalline Nanostructures Symposium at 49th SES Meeting (Abstract Deadline: April 2, 2012)

Dear Colleagues,

 

We would like to bring your attention to the Mechanics of Crystalline Nanostructures Symposium at the 49th Society of Engineering Science (SES) Meeting at Georgia Tech on October 10-12, 2012.   

 

PhD position - Modelling of confinement and interfacial effects in small scale plasticity

The project is based on the well-known size effect exhibited by metals, i.e
the fact that their strengths are greatly enhanced when at least one
microstructural lengthscale is scaled down to the nanometer range or
when the size of the object is restricted to the micron or sub-micron
range. At these scales the interfaces and their associated properties
play a significant role. This project will focus on the effect of
spatial confinement on the three most common deformation mechanisms:
dislocation glide, mechanical twinning and mechanically-induced
martensitic phase transformations; and will be based on the synergies
between physically-based phenomenological modelling using
strain-gradient plasticity at the highest scale, and thorough
