OTEST – „Innovative opto-numerical system for plane displacement measurements and analysis of mechanical properties of materials and structural elements in diverse environmental conditions”

The project is performed as a part of INNOTECH Programme entitled: „Innovative opto-numerical system for plane displacement measurements and analysis of mechanical properties of materials and structural elements in diverse environmental conditions.” The project has started on July 2014 for 48 months and is carried out by the consortium of 3 partners:

  • Astri Polska (leader)
  • Faculty of Mechatronics of Warsaw University of Technology
  • Institute of Aviation

The goal of the project is to develop an optical system for in-plane and out-of-plane displacement/strain measurements and for characterization of material properties. The system will compromise of two optical modules for non-invasive measurements and software for calculating material constants. This approach is called combined numerical-experimental technique.

The system will allow:

  • anisotropic materials examination;
  • surface strain examination;
  • damage propagation examination;
  • static and fatigue examination;
  • examination of sample placed in environmental chamber
  • measurement of strain/displacement of engineering objects

Hardware aspects of the project will be based on:

  • analysis and selection of optical field techniques for measuremen of quasi-flat surfaces;
  • modification of the selected techniques to enable their usage in designed measurement;
  • development of the optical, opto-mechanical and electronic modules that are parts of OTEST system;
  • development of OTEST system software;
  • development of software responsible for processing and analysis of measurement data.

OTEST system applications:

  • Non-destructive measurement methods enhanced by numerical analysis
  • Verification of the boundary conditions
  • Examination of local gradients of strain/displacement due to material non-homogeneity of the sample
  • Examination of cracks and defect propagation mechanics
  • Theoretical or numerical model assumptions verification
  • Examination of elements made of a particular material
  • Obtaining material constants of examined materials

Project co-financed by the European Regional Development Fund
under the Operational Programme Innovative Economy
