Abstract: A glass stress test method includes breaking a glass, analyzing a shape of a crack of a broken portion of the glass in a plan view, finding a breakage origin of the glass based on the shape of the crack in the plan view, analyzing a cross-section of the breakage origin, and calculating a stress of the glass based on a cross-sectional analysis result of the breakage origin. The stress of the glass is calculated as a value proportional to a floor constant defined by a condition of a floor surface disposed when the glass is broken.

Abstract: The present invention relates to the technical field of equipment for impact tests; more specifically, to an instrumented pendulum for Charpy-type impact tests on miniaturized samples. The instrumented pendulum (1) for miniaturized Charpy impact test, according to the present invention, is characterized in that it comprises a main monolithic part, a cleaver (7) housed in an anterior opening of the main monolithic part, and the at least two additional plates (11, 12) removably attached to the respective sides of the main monolithic part of the instrumented pendulum (1). Further, the present invention relates to a Charpy impact machine comprising the instrumented pendulum (1) and an automatic device (6) for releasing the instrumented pendulum (1) at different values of firing angle.

Abstract: A device to intercept a falling ball and prevent a second impact in a hardness or other test of a product and a falling ball impact tester including the device are disclosed. The device includes a sensor for detecting a position of the falling ball, an interception plate defining a catching groove, and a driving member connected to the interception plate and the sensor and providing motion. The driving member can move the interception plate to a position where the catching groove is in a falling path of the falling ball or is just outside such path, according to detection by the sensor.

Abstract: An impact test apparatus includes a base plate having an upper surface on which a specimen is placed, a collision member that collides with the specimen, a dropping unit that drops the collision member from an upper area of the specimen to the specimen and adjusts a height that the collision member drops, a velocity measurement unit that measures a collision velocity of the collision member when the collision member collides with the specimen, and an evaluation unit that produces a representative value that is a collision velocity at which a probability of breakage of the specimen is about 50%, and evaluates an impact resistance of the specimen based on the representative value.

Abstract: A drop tower apparatus and method of use is provided. The drop tower apparatus includes a base, a frame, a top member, rails, a sled, a triggering system, and a test fixture. The frame extends from the base. The top member is disposed on the frame opposite the base and has a winch. The rails extend from the base to the top member and are disposed within the frame. The sled is configured to slide vertically along the length of the rails and is releasably connected to the winch of the top member. The test fixture is configured to receive a sample for testing. The winch of the top member raises the sled to a desired height, the sled is released at the desired height and slides along the rails resulting in an impact on a sample placed in the test fixture.

Abstract: A falling-object protective structures (FOPS) test assembly for carrying a FOPS test of a wall of cab of a heavy vehicle is configured to releasably carry a test ball for the FOPS test above a predefined distance above wall. The FOPS test assembly defines a closed path for test ball from its housing position to wall, and includes a handling means configured to assume a first condition in which they do not interfere with the passage of test ball through the closed path when ball passes through closed path in a first direction and a second condition in which handling means lock and hold test ball within the closed path once test ball passes again through the closed path in a second direction opposite to the first direction.
