Abstract

A material testing machine, including a machine body, a first fixing element, a second fixing element and a detection assembly; the first and the second fixing elements are mounted to the machine body, the first fixing element is configured to mount a first testing element, and the second fixing element is configured to mount a second testing element; in a first state, the first and the second testing elements are in sliding contact; in a second state, the first fixing element drives the first testing element to collide with the second testing element; the detection assembly is configured to detect a target parameter, and in the first state, the target parameter includes a friction force and/or, a friction sound between the first and the second testing elements; and in the second state, the target parameter includes a collision force received by the first or the second testing element.
