Specific features of strain measurement in composite materials

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusion

In strain measurement in composite structures, it is necessary to remember that the longitudinal and transverse sensitivity coefficients of the sensors must be experimentally determined and the results of strain measurement must be processed using these coefficients for obtaining a reliable result for each batch of sensors investigated; the base of the sensors must be one order of magnitude larger than the characteristic size of the surface roughness of the material; during tests with a temperature varying in time, the force-balance transducer must be placed on CM with a structure identical to the CM on which the working sensor is placed; an apparatus with a brief sensor sampling time must be used for materials with a low thermal conductivity.
