The objective of this paper is to show the application of moire fringes method to investigate the distribution of plastic strains and the plastic deformations in plates subjected to the bearing stress in bearing type connection. The variations in mechanical properties of connected plates are SS41 and SM58, and variations in plates shape, i.e. e_1/D=(S-D)/D (See Fig.12) are ranging from 1.5 to 3.5. Results are reported of 60 tests on bolted connections applied to moire fringes method. From these tests and analyses of moire fringes, the following subjects were investigated. 1) Consideration about the plastic strain distribution of the plates. 2) Classification of the ranges of plastic strain states of the plates. 3) The features of load (stress)-displacement relation-ship on the connections. 4) Examinations of allowable stress and allowable values on bearing type connection.
