About This Conference

Nano- and micromechanical testing is an established, but still emerging field which strongly contributes to materials research and development. A key breakthrough in the field has been the development of nanoindentation testing, also called instrumented indentation testing, which enables a precise control of forces on displacement on the nanoscale. Besides indentation, today’s nano- and micromechanical methods include compression, tension and bending tests, thin film testing methods, different in situ testing techniques as for example micro-bending experiments combined with diffraction methods like EBSD or X-rays. Moreover fatigue loading and fracture mechanical experiments are performed on small length scales to study deformation processes and determine the local mechanical properties.

The samples for these test methods are prepared by various techniques, ranging from focused ion beam, to lithography, etching of thin film and also femtosecond laser processing, or growth of micro/nano-objects (whiskers, rods, spheres, etc.). Recently these tests were able to effectively reach the theoretical strength of various nanowires, which opens the way to work with unprecedented stress states of metals or semi-conductors. New developments have been reported in achieving local testing at high strain rates and elevated as well as low temperatures.

Testing at small length scales leads to size effects in the mechanical response, where the microstructural length scale and sample size are very important. Modeling of the mechanical behavior is of special importance to gain an improved understanding of the measurements and underlying deformation mechanisms in the various test methods. For example, discrete dislocation dynamics, molecular dynamics or crystal plasticity finite element simulations provide meaningful and quantitative insights into the deformation processes around nanoindentations and small scale samples. Furthermore, small scale mechanical testing is now used as one approach for validating integrative computational material engineering, since the same length scales can be addressed both in experiment and modelling.

Applications of these nano- and micromechanical testing methods have become more and more important in all fields of materials research like metals, ceramics, glasses, polymers, coatings, composites, and biomaterials and will improve our understanding of the complex mechanical behavior in small scale. Besides hardness the visco-elastic behavior or time dependent properties, phase transformations, fracture phenomena and toughness can be quantitatively evaluated with the new test methods. For many applications, the temperature and rate dependence and other environmental parameters such as hydrogen are of great interest. These nano- and micromechanical testing techniques will help in the development of design concepts for materials based on their local mechanical properties.

This conference will bring together people working in the field of nano- and micromechanical testing in materials research. It will provide a forum for discussion of the latest activities in application of nano- and micromechanical testing methods. The conference is a continuation of the ECI series.

  • 2005 – Instrumented Indentation Testing (Crete, Greece),
  • 2009 – Nanomechanical Testing (Barga – Tuscany, Italy),
  • 2011 – Nano- and Micromechanical Testing in Materials Research and Development III (Canary Islands, Spain),

  • 2015 – Nanomechanical Testing in Materials Research and Development V (Albufeira, Portugal).

The major topics to be discussed are:

  • Fundamental studies in mechanical and indentation testing (size effects, phase transformations…)
  • FIB/lithography based nano- and micromechanical testing
  • In-situ techniques (synchrotron, electron microscopy, light microscopy…)
  • Deformation mechanisms
  • Modeling with focus on molecular dynamics, discrete dislocation dynamics and crystal plasticity
  • Combination of modelling and experiments for prediction of macroscopic behavior based on local testing
  • Novel preparation methods for micro- and nanoscale objects suitable for mechanical testing
  • Testing of nanostructures, thin films and coatings
  • Fatigue and fracture testing
  • Testing of polymeric and biomaterials
  • Testing of metals, ceramics and composites

General Information about ECI

Engineering Conferences International (ECI) is a not-for-profit, 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 conference provides morning and late afternoon or evening sessions in which major presentations are made. Poster sessions will be scheduled for evening discussion as well. 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 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.
