TC15 - Experimental Mechanics

Beyond the classical fields of static, dynamic and stability problems in experimental mechanics a wider field of application must be opened to analyze the problems of geometric and physical non-linearity, to consider time-depending response of materials and structures, to study the effects of elastic-plastic, video-elastic and video-plastic as well as of inhomogeneous and non-isotropic response of materials, to study the phenomena of fracture and fatigue. Moreover, analyzing the effects of impact loading, wave propagation, experimentally, as well as measurements in modal analysis and systems identification and their evaluation are within the scope of experimental mechanics. According to recent trends it may also be of increasing importance to deal with measurements in biomedicine, as far as these have to do with strains in human skeletons, in joints of the skeleton and in the artificial substitutes. The activities should also contribute to the unification of methods and terminology as well as to principles in teaching and education.

TC16 - Pressure and Vacuum Measurement

Pressure transducers, also differential pressure transducers are widely used in the processing industry, not only to measure the pressure, but to control the process. Special problems occur at high pressure level (e.g. 100-800 bar with differential pressures of 10-1000 mbar). The Committee's objectives are to organize symposia, workshops, round table sessions, etc. on pressure measuring techniques, application, sensor design and possibly, calibration. Practice shows that there is an increasing necessity to carry out international intercomparisons of calibration devices for differential pressure sensors at high pressure levels.

TC17 - Measurement in Robotics

The TC's main objective is to deal with all aspects relevant to robot sensors, both internal and external ones, such as force sensor, tactile sensor, distance sensor, visual sensor and others, employed in robot motion and navigation control-principle, methodology and applications. Communication sensors interfacing between man and robot are also included.

Measurement techniques needed in the field of civil engineering: surveying tasks and supervision during construction, research and development of new materials, systems and methods, analysis, maintenance and monitoring of structures.
Structure health monitoring is of major and growing importance for the construction industry: today poor assessment, only nearly visual and highly subjective, for the future automatic inspection by means of innovative measurement techniques.
Scopes of monitoring: deformation and force measurement, concentration of chemical species as moisture, chloride, pH, etc., corrosion, sensor development is essential (data acquisition, evaluation have to be improved, strategies and decision making are required).
Highlights of TC work in the future: improve sensor development and monitoring strategies, build an interface between metrology (measurement engineering) and civil engineering.

TC21 - Mathematical Tools for Measurements

To promote the harmonisation, the co-ordinated use and the development of new mathematical and statistical tools for measurements, and their implementation in guides, procedures and codes, acting as a portal on an international environment.

TC22 - Vibration Measurement

The objective of TC22 is to provide metrologists in the field of shock and vibration with an international forum for scientific information exchange. Thereby it promotes the latest developments and achievements in the field and enables researchers to do their work more effectively.
The title of TC22 “Vibration Measurement” is meant to enclose the the measurement of the dynamic quantities displacement, velocity and acceleration not only if encountered in a periodic form, but also as static or transient measurands (e.g. shock). The motion sensed may be translational as well as rotational (angular vibration). The areas of scientific interest are best explained by the collection of keywords below.

TC23 - Metrology in Food and Nutrition

Food and Nutrition (F&N) metrology is an emerging discipline that is helpful in strengthening the reliability of analytical data, and integration of metrological concepts into the measurement process is the need of the hour. This step is necessary also to ensure sustainability of the analytical QA process. These tasks are looked upon as a twin assignment under TC-23:

(i) enhancing the reliability of F&N measurements by introducing metrological concepts, and
(ii) strengthening the metrological capability of the professional pool (capacity building for young investigators), since the academic system in the F&N areas generally do not provide for adequate training that includes teaching metrology.

The TC-23 focuses on addressing a variety of metrological issues connected with food and nutritional measurements, e.g. food safety assays and relevant inorganic chemical metrology aspects.
