Instrumented pendulum for miniaturized Charpy impact test and Charpy impact machine comprising the instrumented pendulum

A Charpy impact machine comprising:

• an instrumented pendulum comprising:
• a main monolithic portion;
• a cleaver, housed in an anterior opening of the main monolithic portion;
• at least two plates, at least one of the at least two plates removably attached to respective sides of the main monolithic portion;
• and
• one or more hollow supports;
• wherein the main monolithic portion and the at least two plates each comprise one or more complementary openings to receive the one or more hollow supports, wherein the one or more complementary openings are aligned with respect to a geometric axis of rotation of the instrumented pendulum;
• a support shaft coupled to the main monolithic portion and a support arm;
• a base connected to the support arm;
• a sample holder attached to the base;
• and
• an electromechanical device, positioned at the geometric axis of rotation of the instrumented pendulum.
