1. A material testing machine, comprising a machine body, a first fixing element, a second fixing element and a detection assembly;
both the first fixing element and the second fixing element 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; when the first fixing element and the second fixing element are in a first state, the first testing element is in sliding contact with the second testing element; and when the first fixing element and the second fixing element are 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 when the first fixing element and the second fixing element are in the first state, the target parameter comprises at least one of a friction force between the first testing element and the second testing element and a friction sound generated due to the sliding contact between the first testing element and the second testing element; and when the first fixing element and the second fixing element are in the second state, the target parameter comprises a collision force received by the first testing element or the second testing element.
