To measure the micro-deformation, the femtosecond laser exposure system was used to fabricate model grids for electron moire method. Microstrain distribution of the laminated steel specimen during three-point bending tested was measured by electron Moire method. Strain concentration near the boundary and nonuniform strain distribution could be observed. The results show that the difference of distributed strain in SUS304 layer is larger is larger than that in WT-780 layer.
