| Abstract: | The theory of moiré interferometery method is introduced.The duplication procedures of specimens grating are discussed.The arrangement of optical accessories and key operation in regulating beam path are discussed emphatically.Specimens of bimaterial of porcelain-fused-metal are studied by moiré interferometery method.Displacement and strain of specimens are obtained in this experiment.In order to check the reliability of results of experiment,results data have been compared to which of finite element method(FEM).The experiment method and experiment process indicated that mechanical behaviors of composite can be studied effectively by moiré interfereometry technology.Simultaneously,the experiment results can be shown direct-vision and contrast highly.So all of data of image picked by charged couple device (CCD) are very necessary for further image processing. |
