Dr. Ted Belytschko of the Mechanical Engineering Department of Northwestern University invites applications for a Post-Doctoral  Fellowships in the area of computational fracture.  Experience with FORTRAN is necessary; some experience with MPI is desirable. Applicants without extensive experience in FORTRAN need not apply.  Furthermore, applicants with experience with DYNA and/or LS-DYNA will be given preference.  The appointment will be for a minimum of two years.   Interested applicants should send their curriculum vitae along with a list of three references to Robert Gracie at rgracie@northwestern.edu

We are no longer accepting applications for these positions.  Qualified applicants will be contacted in the near future.  

Thank you for your interest,

 Robert Gracie

Abstract:

A new technique for the modelling of multiple dislocations based on introducing interior discontinuities is presented. In contrast to existing methods, the superposition of infinite domain solutions is avoided; interior discontinuities are specified on the dislocation slip surfaces and the resulting boundary value problem is solved by a finite element method. The accuracy of the proposed method is verified and its efficiency for multi-dislocation problems is illustrated. Bounded core energies are incorporated into the method through regularization of the discontinuities at their edges. Though the method is applied to edge dislocations here, its extension to other types of dislocations is straightforward.
