Dr. Stewart Silling has provided me with a copy of his talk on Peridynamic theory that he presented at McMat 2007. The PDF file of the talk is attached below.
In order to deal with classical material models and volume constraints, Dr. Silling has modified the original theory to allow for forces that are not necessarily pairwise. A bit on that is included in the talk.
The group of Mechanics &
Computation in the Mechanical Engineering department at Stanford University has
an opening for a postdoctoral position in the area of computational mechanics
as part of the new Army High-Performance Computing Research Center (AHPCRC),
under the direction of Adrian Lew. The appointment
is normally made for one year, with the possibility of renewal for a second
year. The ideal candidate would have a strong background on
computational solid mechanics and have programming experience, ideally in C++.
A good background in mathematics, especially numerical analysis, will be
If possible,share your opinion (idea) about the future trend of fracture mechanics. Thanks!

Dear Colleague,
We want to draw your attention to and encourage your participation in a special session on Multiscale Modeling and Simulation of the thirteenth Pacific Symposium on Biocomputing (PSB), to be held January 4-8, 2008, on the Big Island of Hawaii. PSB is an international, multidisciplinary conference with high impact on the theory and application of computational methods in problems of biological significance.
Abstract |
This paper presents an anharmonic lattice statics analysis of 180 and 90 domain walls in tetragonal ferroelectric perovskites. We present all the calculations and numerical examples for the technologically important ferroelectric material PbTiO3. We use shell potentials that are fitted to quantum mechanics calculations. Our formulation places no restrictions on the range of the interactions. This formulation of lattice statics is inhomogeneous and accounts for the variation of the force constants near defects.
