About This Conference

Overview:  Environmentally-Assisted Cracking (EAC) of engineering materials has been known for at least a half century.   The sensitivity of engineering alloys to environmental exposure is well known from an engineering perspective.  What is not known with certainty at this stage are the mechanisms of initiation and propagation by which the many manifestations of EAC occur.  This understanding is fundamental to the development of strategies for control and prediction of EAC failures and is of great importance to the failure communities.

While significant progress in our understanding of EAC has been achieved in recent years, important fundamental questions remain on both its initiation and propagation.  For instance, the questions “how does the environment influence the crack driving force,” and “why do ordinarily ductile materials fail in a brittle manner when exposed to certain environments” remain unanswered.

Our objective is to congregate a group of “skilled in the field” researchers in metallic materials for a workshop style that will endeavor to help clarify our current understanding of EAC and identify approaches to improve the current semi-quantitative understanding of the mechanisms.

The emphasis of the papers will be on:

  • systematic evaluation of the governing interacting parameters for crack initiation and propagation, including the roles of the local alloy microstructure, local crack morphology/branching, local environmental conditions within cracks and the local mechanical driving forces. • papers including experimental data for crack initiation and/or growth and those exploring unifying principles governing these time-static/cyclic stress dependent crack growth phenomena are particularly welcome;
  • new techniques for measuring crack initiation in aqueous environments;
  • the emphasis is on understanding and quantifying, rather than reporting the data of some material response;
  • all topics are to be at ambient temperatures.

Scope:  The scope of this symposium includes the fundamental understanding of EAC from the initiation stage to growth and final failure in engineering alloys.

Emphasis of papers will be on the systematic evaluation of mapping governing parameters, such as thresholds stress intensity factors, crack growth rates, and steady state behavior.  Papers dealing with unifying principles governing the time-stress dependent crack growth phenomena are particularly welcome.

Papers that are related to composite materials are discouraged.

Technical Topics:

  • Systematic variation of threshold KIscc and steady state (da/dt) in aqueous and gaseous environments
  • Role of damage under static load and fatigue loads in inert and in chemical envronments
  • Role of internal/external hydrogen on threshold K and crack growth
  • High resolution evaluation (ideally 3D) of Crack tip local conditions: mechanical driving-forces, alloy microstructure and environmemtal conditions
  • Modeling of the governing mechanisms-atomistic & continuum
  • The convergence of simulation and modeling with modern analytical tools

Conference Venue

The conference will be held at Schloss Hernstein Seminar Hotel. The hotel is situated in the wonderful Triestingtal valley, surrounded by pine forests and a carp lake. Guests can enjoy sauna, steam and fitness rooms, as well as a large indoor swimming pool. There are also several signposted routes for jogging on forest tracks starting at the hotel.

Brochure describing the history of Schloss Hernstein:          Part I                    Part II

Hernstein Castle is situated at the fringe of the Viennese Basin, in the stepped footland of the Styrian and Lower Austrian limestone alps. Its history goes back to medieval times: once the castle safeguarded the street to Berndorf Village and the valley before it. In former times the building comprised a housing unit and a chapel. It would have been very difficult to expand the building; therefore a new castle – the core of today´s castle – was built in the valley at the foot of the mountain where the old castle had been built.

After the Turkish wars this new building was expanded and in the 18th century it got a uniform facade. For a long time the castle was owned by the Habsburgs and was used as domicile by Archduke Leopold Ludwig. The renowned architect Theophil Hansen designed the castle.

Hernstein Castle is one of the largest seminar hotels in Austria and is only available to seminar participants. Therefore it ensures a tranquil atmosphere of learning and working. Hernstein Castle has 74 modern bedrooms. Room amenities include sky and satellite TV, a minibar, work desk, and wireless internet.

General Information About ECI

Engineering Conferences International (ECI) is a global engineering conferences program, originally established in 1962, that provides opportunities for the exploration of problems and issues of concern to engineers and scientists from many disciplines.

The format of the weeklong research conference provides morning and late afternoon or evening sessions in which major presentations are made. Available time is included during the afternoons for ad hoc meetings, informal discussions, and/or recreation. This format is designed to enhance rapport among participants and promote dialogue on the development of the meeting. We believe that the conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums.

All participants are expected both to attend the entire conference and to contribute actively to the discussions. The recording/photographing of lectures and presentations is forbidden. As ECI conferences take place in an informal atmosphere, casual clothing is the usual attire.
