Abstract

The invention discloses an apparatus for testing micro-nano structure mechanical properties of a material, characterized by comprising a laser speckle interference test unit, a visual guide and speckle image related test unit, a right positioning sliding table, a micro-displacement drawing machine, a two-dimensional positioning sliding table, and a left positioning sliding table. The apparatus has the properties such as high speed, high precision and non-contact whole-field test, and therefore, the need of various materials for actual test on micro-nano structure mechanical properties is met.

Description

technical field [0001] The invention relates to optical testing of mechanical performance parameters of materials, in particular to a testing device for mechanical mechanical performance of material micro-nano structures. Background technique [0002] The characteristic length of the material micro-nano structure sample is generally on the order of millimeters. Compared with the conventional size, its mechanical properties will change significantly. At present, there is a lack of detection of its mechanical properties. The dispersion of the mechanical properties of the material micro-nano structure is tested. It is very large, and a complete testing system and standards have not been formed. For the detection of material micro-nano structure specimens, many traditional testing methods and testing instruments will no longer be applicable, and the tinyness of the specimens also brings a series of difficulties to the experiment, including the clamping, centering and loading of ...
