Paper Abstract

Introducing into industry numerous mechanical joints produced by new technologies and combining new materials requires careful determination of their properties. In the paper the material constants and residual strain distributions in the analyzed structures are determined and their applying in the hybrid experimental-numerical method is considered. Application of automated moire interferometer for measurement of local Young's module, Poisson ratio and residual stresses released by cutting are described. The process of reduction and transferring of experimental data into FEM model is presented. The examples of laser weldment and ceramic-to metal joint testing are shown.
