摘要： A hardness tester for a large test material is downsized by shortening a stroke length of the x-y stage. A hardness tester in accordance with the invention transfers the laser irradiating unit 70 two-dimensionally along the X or Y axis and irradiate a laser beam on the material W under test placed on the stage 10. The tester also monitors the laser beam visually and determine a target position to be measured and transfers the monitoring unit 45 to the determined target position along the X or Y axis and monitor the position by means of the monitoring unit 45. If the position does not fall on a boundary between crystals, the loading unit 55 is two-dimensionally transferred and forms a dent on the position by means of the penetrator 55a. An image of the dent is captured by the monitoring unit 45 and the hardness is determined by calculating a diagonal length of the dent by image processing.

摘要： A method and an apparatus for determining the resiliency of a road surface include a vehicle (1) that is caused to move along the road surface (3) and that exerts a load on said surface with one wheel (2). A ball of plastic material (16) is shot onto the road surface (3) so as to adhere thereto in the movement path of two measuring arrangements (8, 9; 18, 19) which are separated in the direction of movement of the vehicle (1) and by means of which the vertical distance is measured between the upper side of the ball (16) adhering to the road surface (3) and a vehicle-carried reference in two positions along the vehicle. The distance between the reference and the measuring body can be established in several positions along the vehicle (1), for determining the deflection curve of the road surface.

摘要： A hardness tester having a frame and a rotatable turret movably supported on the frame is provided. A plurality of load cells are fixedly mountable on the turret, and a plurality of indenters are fixedly attachable to the load cells, respectively. A user interface selectively provides signals to a motor to move the turret into contact with a test specimen via one of the indenters to thereby apply a load on the test specimen. The indenters are fixed with respect to the turret and do not move in relation to the turret when the turret is brought down to bear on the test specimen. The load cells measure the load applied to the test specimen. A closed loop control system receives load measurement signals from the load cells and controls movement of the turret, preventing the motor from applying load in excess of a predetermined selectable load amount input by a user via the user interface. The invention preferably includes a plurality of indenter adapters, each attached to respective undersides of the load cells. Each indenter adapter includes a slot into which the indenter is fittable, and least one set screw for adjusting a horizontal location of the indenter.

摘要： An indentation measurement apparatus is retrofittable onto any of a variety of load-applying frames and includes a mount for mounting an indenter of any geometry (for example blunt or sharp). The arrangement is very stiff and mechanical values including Young's modulus, strain hardening exponent, yield strength, and hardness can be obtained from a single load/unload versus displacement test. A wide variety of materials can be tested using the apparatus. An optical probe can measure displacement of the indenter head relative to a sample. A new method of calculating strain hardening directly from load/displacement measurement is presented as is a new method of calculating strain hardening exponent.
