EU Funds

SHM System implements the following projects financed by European Funds:

1. “Stress Damage Detector”
SHM System Sp z o.o. Sp. kom. received co-funded by the European Union grant as a part of the European Funds for Smart Economy programme, Priority: Support for entrepreneurs, Activity: SMART Pathway

The subject of the project is the development and implementation of a unique in the world detector into the SHM System portfolio. The Stress Damage Detector allow to indicate the moment when these stresses are reached, but before they are exceeded and before the material failure. The detector will take a form of fibre optic strain sensor made in DFOS (Distributed Fibre Optic Sensing) technology. The detection of the moment of occurring the damage stress is based only on the measurement of concrete strain, without any additional information, in particular without knowing the type of concrete, its strength characteristics or the value of initial stresses in the concrete in the area where the sensor is installed. The detector’s operation is based on a proprietary method for analysing the proportionality of strain of the monitored material, developed by SHM System.
The main task of the project is to determine the mechanical and structural parameters of the detector so that the detection of the moment of concrete failure is independent of the spatial direction of the sensor installation in the concrete, the grain size of the aggregates and the presence of reinforcement. The research will be based on numerical FEA analyses and experimental tests on testing stands.
The result of the project will be a fibre optic sensor allowing for indication when stress in concrete reaches a destructive level, but before the material failure. The innovative detector will be used in Structural Health Monitoring (SHM) systems, in particular in building critical infrastructure in terms of the consequences of its failure or destruction. This means that the product will indirectly serve to increase the safety of all citizens worldwide.
The product can also be used for laboratory research by research institutes and universities. The result of the project will also increase the potential and competitiveness of SHM System as a company offering top-quality solutions for Structural Health Monitoring of engineering structures.
Total cost of the project – 14,098,300.00 PLN
Value of co-funding from European Funds – 10,960,718.34 PLN

Work on the project “Stress Damage Detector in Concrete (SDD)” is ongoing. Scope of the work carried out in the first stage:
Research equipment was acquired and launched, i.e. a research station for preparing concrete samples, 3D printing of sensor cores using the Zero Waste method and a station for strength tests. In the scope of FEM model tests, a concrete sample model was made in the Sofistik program. The model was built taking into account two fractions of the material that makes up concrete, i.e. cement and aggregate. Its validation is currently underway. Due to two material characteristics, this task turned out to be more laborious than expected at the beginning of the work. Out of caution, it was decided to make a second FEM model in the SALOME/Code-Aster program, where a concrete model made of a homogeneous material with characteristics obtained in strength tests was adopted.
Without waiting for the completion of the FEM model work, experimental tests of samples were started for measurements performed in one and two planes, the directions of measurements were initially determined experimentally and samples for testing were made. A series of experimental tests were carried out with sensors placed in one plane, for which the minimum number of strain measurement directions was determined to allow detection of the moment of concrete failure. Currently, experimental tests of measurements in two planes are underway and preparations for experimental tests in three planes have begun. The obtained results allow for correct detection of the moment of concrete failure, but they are not yet optimal in terms of the sensitivity of the indicator. The obtained, initial directions of the detector measurement will be corrected after the completion of the FEM tests and experimentally tested again in order to compare their effectiveness with the results obtained experimentally.

2. “FBG sensor for non-uniform strain control”
The subject of the project is the development and implementation into the activity of the Applicant, a uniąue in the world FBG sensor allowing the measurement of non-uniform strain field in non-homogeneous materials. The main task of the project is to determine the mechanical parameters and geometry of the coating transmitting deformations to the long Bragg grating and to develop a germanium-doped fibrę with modified stiffness modulus, while maintaining the sensor’s interoperability with standard measurement devices used in the market. The value of the project is 8,875,126.25 PLN, including the contribution of European Funds: 7,330,815.50 PLN.

3. “A critical stress detector for steel pipelines
The aim of the project is to develop and implement world unique technology for the detection of critical states of stress in steel pipelines. The analysis of numerical models of the yielding phenomenon (FEM modeling) and experimental testing on test stands were selected as the main research methods. The detector developed within the framework of the project, in the form of a sensor band, together with the technology of its application, will enable monitoring of the technical condition of pipeline structures within the scope which has not been available so far and will provide key data, from the point of view of the assessment of the safety of the pipeline operation, on the stress state of the pipeline with the unambiguous signaling of critical stresses – yielding. The value of the project is 15,508,765.00 PLN, including the contribution of European Funds: 11,288,081.95 PLN.

4. “PDS – Plastic deformation sensor
The result of the project will be a plastic deformation sensor – the world’s first plasticization sensor (hereinafter PDS) for detecting the moment of yielding of the material in situ. The solution will allow to unambiguously determine the time when the material reaches the limit of elastic deformation and starts to work in the field of plastic deformation (yield point). The sensor will detect yielding only on the basis of the obtained measurement data, without knowing the strength characteristics of the material, the technical condition of the structural element and its initial state of deformation. The value of the project is 6,437,105.00 PLN, including the contribution of European Funds: 5,010,709.00 PLN.
