The method for detecting bending stiffness includes: arranging an object to be tested on a reference surface to make a stationary portion and a rotating portion of the object to be tested attached to the reference surface, the stationary portion and the rotating portion being connected to each other; driving the rotating portion to bend from the reference surface toward the stationary portion, and acquiring a rotation angle between the rotating portion and the reference surface; acquiring a bending force received by the rotating portion when the rotating portion is bent from the reference surface toward the stationary portion; and determining bending stiffness of the object to be tested on the basis of the bending force and the rotation angle.

According to the embodiments disclosed herein, in a press-fitting test for measuring physical properties of a test object by pressing an indenter against the test object and measuring the load and displacement, the measured displacement value is corrected in real time in consideration of the amount of deformation according to the load of the load cell, and thus an accurate load-displacement curve can be derived, even when the amount of deformation of the load cell is included in a measured value of a displacement sensor.

An indentation head system for an indentation instrument includes: an indenter tip contacting a sample surface along at least an indentation axis; a reference element supporting the tip; a zero-level sensor generating a signal indicating whether the tip is displaced with respect to the reference element from a neutral relative position; an elastic element between the tip and an actuator with known elongation, the actuator connected to the reference element; and a controller receiving signals from the zero-level sensor to perform servo control of the actuator based on output of the zero-level sensor and the known elongation of the actuator so the zero-level sensor outputs a signal corresponding to a substantially zero displacement of the tip from the neutral relative position, the controller calculating a force applied by the tip to the sample based on an output of the displacement sensor and an elastic coefficient of the elastic element.
