Slow-Fast Crack Propagation in Ferroelectric Single Crystals

Dear Colleague,


I have uploaded a video which shows the simulation of Slow-Fast crack propagation in ferroelectric single crystals:


For technical details, please refer to our recently published paper in Acta Materialia:

Four-year PhD position on modeling of irradiation-induced embrittlement

The Micromechanics of Materials group at the Zernike Institute for Advanced Materials in the Netherlands is looking for a qualified PhD student to unravel irradiation-induced embrittlement in nuclear materials. A detailed description can be found in the attachment. Ideally, candidates have an MSc degree in mechanical or nuclear engineering, (applied) physics, material science or a related field, but holders of a BSc with the highest ranks may also be considered.

Apply before it's too late: June 1.

Damage tolerance of railway axles

Failure of railway axles has been the problem which gave origin to the studies about 'fatigue'. The modern approach to the structural integrity of these safety components is to complement the traditional designwith a 'damage toleranc' analysis.

Postdoc research associate and PhD student positions available

One postdoc and several PhD student positions are available at Clarkson University. Research background in at least one of the following areas is preferred.

1. Fatigue and fracture of materials and structures, computational mechanics and numerical methods

2. Probabilistic methods, Bayesian statistics, reliability and risk assesment 

3. Structural dynamics, health monitoring, signal processing, system identification

A blog for discussing fracture papers

The aim of ESIS is not only to develop and extend knowledge in all aspects of structural integrity, but also to disseminate this knowledge world-wide by means of scientific publications and to educate young engineers and scientists.

A free program to generate interface elements in an existing FE mesh

Hello all,

Last year when I started implementing interface elements to model material failure, I realized that the formulation is easy except how to generate a mesh with interface elements. I did a googling to search for such a free program. Amazingly, I did not find any although there are many researchers working on the fracture mechanics field.

So, I wrote a small object-oriented C++ program which reads a FE mesh, duplicates nodes and insert interface elements where asked. The program is able to

(1) insert 1D/2D interface elements everywhere in a FE mesh

Mechanics of Materials: Textbook Recommendation

I will be teaching a sophomore level class  mechanics of materials class.  The class will cover mechanics of basic strength of materials (e.g. beams, pressure vessels), but I also want to teach basic elements of failure mechanics (fracture, fatigue, plasticity, and wear.)  I'm looking for a recommendation of an undergrad mechanics textbook that covers the fracture, fatigue, plasticity, and wear.  The students will have had a statics and mechanics class and their textbook already covers strength of materials.  Thanks.

Fracture of electrodes in lithium-ion batteries caused by fast charging

During charging or discharging of a lithium-ion battery, lithium is extracted from one electrode and inserted into the other.  This extraction-insertion reaction causes the electrodes to deform.  An electrode is often composed of small active particles in a matrix.  If the battery is charged at a rate faster than lithium can homogenize in an active particle by diffusion, the inhomogeneous distribution of lithium results in stresses that may cause the particle to fracture.  The distributions of lithium and stress in a LiCoO2 particle

How do ductile materials fail?

This is a review on ductile fracture committed to the Advances in Applied Mechanics (Vol 44). Part of the review has an educational purpose and, as such, is intended for advanced undergraduates and starting graduate students. The other part is an account of recent research conducted in the field.

Though quite long, the review is by no means exhaustive. As noted in the discussion, many valuable contributions to this field have been left out. The focus was laid on micromechanics-based approaches to connect to microstructural aspects in engineering materials.
