Abstract
Provided is a material testing machine capable of giving an appropriate testing force to a testing piece. The material testing machine performs a three-point bending test on a testing piece and includes a support mechanism that supports the testing piece, an indenter that is connected to an ultrasonic oscillator and gives ultrasonic vibration to the testing piece by abutting against the testing piece, and a load mechanism that presses the indenter to the testing piece supported by the support mechanism. The support mechanism includes: a spherical seat that has a lower member equipped with a spherical-surface-shaped concave portion or convex portion, and an upper member equipped with a spherical-surface-shaped concave portion or convex portion having a shape corresponding to the concave portion or convex portion in the lower member; a holding portion; and a first movable member.
