mini-symposium on Multiscale and Plasticity Models of Energy Related Materials

Dear Colleagues,

I would like to invite you on behalf of myself, Prof. Tahir Cagin (Texas A&M) and Prof. Akhtar Khan (University of Maryland) to contribute to a newly added mini-symvposium to the International Symposium of Plasticity to take place 3-8 January 2013 at Bahamas Island; more detailed information of the event is listed below.

Finite element analysis of the spherical indentation of transversely isotropic piezoelectric materials

Finite element analysis was used to analyze the indentation deformation of
a transversely isotropic piezoelectric material (PZT-4) by a rigid spherical
indenter. Three cases were considered in the analysis, which included (a)
the indentation by an insulating indenter, (b) the indentation by a conducting
indenter and (c) the indentation of the piezoelectric material with equal electric
potential on the top surface. The indentation load was found to be proportional
to the 3/2 power of the indentation depth for all three cases. Using the simulation
