Abstract

This invention relates with a portable crack testing device that comprises a sliding rail where a movable base is disposed on a movable mean of the rail such that the movable base is movable on the sliding rail; a force sensor fixedly attached to the movable base; a blade base fixedly attached to the sensing area of the force sensor; a blade, for applying force to a test material, fixedly attached to the blade base such that the blade protrudes from the force sensor and aligns with a test slit of a material holder, allowing the force sensor to measure pressing force when the blade is applied onto a test material; wherein a control unit processes the force value measured by the force sensor, the elongation of the test material that is analyzed from the displacement of the blade when pressing on the material, with material cracking information database to determine the chance of the test material to be cracked.
