Abstract: An apparatus and a method for in-situ testing impact strength of a micro-structure are provided. In one embodiment, the apparatus includes: a flexible beam, one end of which being fixed; an impact mass block disposed at the other end of the flexible beam and being for exerting an impact on the micro-structure; and a locking member including a beam arm and a plurality of locking teeth. The beam arm is perpendicular to the flexible beam and one end of the beam arm is fixed, and the plurality of locking teeth are distributed at intervals along the beam arm, such that the other end of the flexible beam is engaged to one of the plurality of locking teeth when the flexible beam is loaded.

Abstract: Disclosed is an apparatus for in-situ testing impact strength of a micro-structure, comprising: a flexible beam, one end of which being fixed; an impact mass block disposed at the other end of the flexible beam and configured to exert an impact on the micro-structure; and a locking member comprising a beam arm and a plurality of locking teeth, wherein the beam arm is perpendicular to the flexible beam and one end of the beam arm is fixed, and wherein the plurality of locking teeth are distributed at intervals along the beam arm, such that the other end of the flexible beam is engaged to one of the plurality of locking teeth when the flexible beam is loaded. A method for testing an impact strength of a micro-structure is also disclosed.
