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.
Job description: We are seeking innovative and highly motivated PhD candidates to join the FROG lab in the mechanical engineering department at the University of Ottawa.
The project is between BITS Pilani (India) and Wuhan University (China), funded by the Ministry of Mines, Govt. of India. It is in the area of computational fracture mechanics.
Details of the project and application process is in the attachment.
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.
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.

We are pleased to announce a mini-symposium on Fracture Mechanics at the 52nd Annual Technical Meeting of the Society of Engineering Science, to be held at the Texas A&M University, College Station, Texas, October 26-28, 2015.
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
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.
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.
