摘  要：
The post-buckling deformation parameters and elastic modulus of elastic materials are important parameters for the characterization of materials' mechanical properties.In order to improve the measuring accuracy and the degree of automation of post-buckling deformation parameters and simultaneous determination of elastic modulus of elastic materials,and to achieve the miniaturization of the testers,human-computer interaction technology,PLC control technology,linear pulse motor drive technology,scanning technology,force measurement technology,computer image processing technology,and other modern technology were integrated together to develop comprehensive detectors for post-buckling deformation parameters and elastic modulus of elastic materials.Meanwhile,determination of post-buckling deformation parameters of elastic materials based on the image processing technology and simultaneous determination of elastic modulus were achieved.Also,it also applied to the evaluation of the flexural capacity of dried straight-type food.And it proved to be feasible and reliable according to results of evaluation experiments.
