Embodiment

[0022] Use Matlab software to generate multiple simulated speckle patterns with different particle sizes and numbers. The simulated speckle pattern is composed of a number of randomly distributed Gaussian spots, and its gray distribution can be expressed by the following formula:

[0023] I ( r ) = Σ k = 1 s I k 0 exp ( - ( r - r k ) 2 R 2 ) - - - ( 1 )

[0024] Among them, s is ...

Abstract

The invention discloses a method for manufacturing high-temperature speckles, which belongs to the technical field of optical measurement mechanics. The method is technically characterized by comprising the following steps of: optimizing simulated speckles; searching for optimal speckle manufacturing process parameters; manufacturing speckles which correspond to different magnification times; conveniently and flexibly printing a speckle pattern onto a polyvinyl chloride sheet by using printing equipment to obtain a mark plate; and forming speckles on the surface of a high-temperature material sample by using a photo-etching method. The method is easy to operate, is easy to implement, and is particularly suitable for researching the macro deformation behaviors of different materials in high temperature environments; and a speckle field can be quantified.

Description

technical field [0001] The invention relates to a method for manufacturing high-temperature speckles, and belongs to the technical fields of photometric mechanics, engineering materials, component deformation and displacement testing. Background technique [0002] With the development of new high-temperature materials and the needs of aviation, power industry and other departments for the deformation measurement and research of in-service high-temperature components, the mechanical properties, deformation state and failure mechanism of materials and structures in high-temperature environments are increasingly valued by researchers. The problem of high temperature mechanics has been a broad, prominent and unavoidable problem in many fields of aerospace engineering. Therefore, the development of deformation measurement under high temperature conditions has become the focus of attention of researchers in the field of experimental mechanics. At present, there are many high-temp...
