The talk will consist of two parts. In the first part, I |
|
will present prior work aimed at developing new |
|
algorithms for materials science applications. I |
|
developed a novel numerical method to optimize the shape |
|
of mechanical parts and maximize their strength. This |
|
optimization problem was extremely challenging as it |
|
involved changing the topology and therefore classical |
|
optimization methods do not apply. A similar idea can be |
|
applied to model shape memory alloys and plasticity in |
|
metals. In this project, the optimization led to the |
|
construction of a tree of laminated microstructures. |
|
Constraints from mechanical equilibrium were used to |
|
construct an adaptive tree and to determine the optimal |
|
number of levels. |
|
|
|
The second part involves more recent work. I will present |
|
the implementation of a new heat flux algorithm to |
|
understand failures in micro-devices in LAMMPS (Large- |
|
scale Atomic/Molecular Massively Parallel Simulator); |
|
LAMMPS is a high performance code which was benchmarked |
|
on Blue Gene L with 90% parallel efficiency. Also I am |
|
currently extending the capabilities of ParaDiS (Parallel |
|
Dislocation Simulator), another high performance code |
|
which has run on 135k processors of Blue Gene L. |
