Ph.D. position in computational solid mechanics

A PhD position is available in the Department of Mechanical Engineering and Engineering Science at the University of North Carolina at Charlotte. The research project is on the multiscale modeling of the stress corrosion cracking. Candidates should have a strong background in continuum mechanics, finite elements and constitutive modeling. Programming experience in Fortran or C++ is required for this position. The starting date for this position is January 2017.

crack propagation in Abaqus (VCCT) with remeshing

I started using VCCT with quarter tip elements in Abaqus (not XFEM). I can solve the problem and get the SIFs.
How can I let the crack grow? Has someone a script for crack growth and remeshing that I can implement?

SIF for an edge crack in mode III

Hi everyone,

 

I am working on the propagation of an edge crack in semi-infinite plate under antiplane loading.

I need to estimate the stress intensity factor KIII at the front of the crack but I can't find a theoretical formula for this purpose. For an embedded crack of length l in an infinite plate under shear stress sigma_23 I can use KIII = sigma23*sqrt(pi*l). But I don't know what I must use in the case of an edge crack.

Review Article: Atomistic Aspects of Fracture

Any fracture process ultimately involves the rupture of atomic bonds. Processes at the atomic scale therefore critically influence the toughness and overall fracture behavior of materials. Atomistic simulation methods including large-scale molecular dynamics simulations with classical potentials, density functional theory calculations and advanced concurrent multiscale methods have led to new insights e.g.

Predicting fracture energies and crack-tip fields of soft tough materials

Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials.

Fracture strength of micro- and nano-scale silicon components

Silicon devices are ubiquitous in many micro- and nano-scale technological applications, most notably microelectronics and microelectromechanical systems (MEMS).  Despite their widespread usage, however, issues related to uncertain mechanical reliability remain a major factor inhibiting the further advancement of device commercialization.  In particular, reliability issues related to the fracture of MEMS components have become increasingly important given continued reductions in critical feature sizes coupled with recent escalations in both MEMS device actuation forces and harsh usage

Temperature induced crack propagation in structured media

This paper describes the propagation of an edge crack in a semi-infinite triangular lattice, consisting of identical point masses connected by thermoelastic links. A change of temperature, represented by a time-periodic series of high-gradient temperature pulses, is applied at the boundary of the lattice. In order to make the initial crack advance in the lattice a failure criterion is imposed, whereby the links break as soon as they attain a prescribed elongation.

A DOCTORAL STUDENT POSITION IN FRACTURE OF SEA ICE

Aalto University School of Engineering in Finland has an open position for a doctoral student in the Arctic Marine and Ice Technology research group at the Department of Applied Mechanics. Our research group studies the behavior of ships and structures in ice, ice mechanics and also assesses the impact of sea ice on the safety of maritime transportation. An important part of our research is experimental work. For that we have excellent possibilities as we operate the Aalto Ice Tank, a 40 m × 40 m ice model basin.
