Ph.D. Position in Computational Solid Mechanics

Submitted by A.Tabarraei on Tue, 10/24/2017 - 03:16

Two PhD positions are available in the Department of Mechanical Engineering and Engineering Science at the University of North Carolina at Charlotte.
The research project is in the multiscale modeling of the stress corrosion cracking. Candidates should have a strong background in continuum mechanics, finite elements modeling and/or molecular dynamics simulations. Programming experience in Fortran or C++ is a big plus. The starting date for this position is January 2018 or August 2018. Interested candidates please send a detailed CV along with the name and contact info of three references to atabarra [at] uncc.edu.

PhD positio

Hello,

I have a PhD position available for a project titled "Asynchronous, Parallel-Adaptive Solution of Extreme Multiscale Problems in Seismology" funded by the U.S. National Science Foundation (NSF). The research involves:

a. Formulation of contact / fracture models (interfacial and/or bulk) for seismic applications, e.g. anisotropic, inhomogeneous rock under dynamic loads.

b. Adaptive spacetime time discontinuous Galerkin formulation for the solution of multiphysics PDEs relevant to this application.

c. High performance computing aspects of the method.

Eigenerosion for static and dynamic brittle fracture

Submitted by Flavio Stochino on Mon, 08/14/2017 - 15:37

Structural Engineering

In contrast to many numerical methods, the eigenerosion approach yields a convenient description of fracture handled in the postprocessing part of a Finite Element Analysis (FEA). Its fully energetic formulation avoids the introduction of extra degrees of freedom to model fracture propagation. Following previous works on eigenerosion, in this publication, a modified formulation of eigenfracture it is introduced, where it is distinguished between compression and tension loaded state. This formulation has the advantage that it relates the crack propagation process only to tensile loading.

The surface-forming energy release rate versus the local energy release rate

Submitted by Bin Liu on Thu, 05/04/2017 - 08:12

research

fracture mechanics

In our just published paper, we identify two ways to extract the energy (or power) flowing into a crack tip during propagation based on the power balance of areas enclosed by a stationary contour and a comoving contour. It is very interesting to find a contradiction that two corresponding energy release rates (ERRs), a surface-forming ERR and a local ERR, are different when stress singularity exists at a crack tip. Besides a rigorous mathematical interpretation, we deduce that the stress singularity leads to an accompanying kinetic energy at the crack tip.

Objective Fracture Parameters and a Paradox for Interface Cracks

Submitted by Bin Liu on Sun, 03/12/2017 - 01:30

research

fracture mechanics

Due to the oscillatory singular stress field around a crack tip, interface fracture has some peculiar features. This paper is focused on two of them. One can be reflected by a proposed paradox that geometrically similar structures with interface cracks under similar loadings may have different failure behaviors. The other one is that the existing fracture parameters of the oscillatory singular stress field, such as a complex stress intensity factor, exhibit some nonobjectivity because their phase angle depends on an arbitrarily chosen length.
