Talk on Local Optimal Polarization

I'm just back from the piezo-workshop 2013, correctly, the 9th Int. Workshop on Direct and Inverse Problems in Piezoelectricity in Weimar, organized by Prof. Tom Lahmer, a former colleague.

On the workshop 2012 and at WCSMO-10 I presented piezoelectric Free Material Optimization (FMO), however, this makes not that much sense for piezoelectricity, as weak material is the generally best and the optimum is just controlled by the lower bound. For elasticity, where stiff material is in general good, this is a complete different story.

Doing orientational optimization, which has the physical interpretation of local polarization, the problem makes much sense and indeed has potential.



Two further examples I want to solve are dynamic problems (can the resonance frequency be moved by polarization, I guess so but it might be a small effect) and a solid auxetic (negative Poisson's ratio) device, what would be really impressing if this is possible.
