Abstract: A wedge-type anchor assembly, capable of meeting cracked concrete testing standards, comprises an anchor bolt component and a substantially C-shaped expansion sleeve component annularly disposed about the anchor bolt component. A plurality of annular grooves, threads, or teeth are disposed only about the forward end portion of the expansion sleeve component, as opposed to throughout the entire axial length thereof, so that when the anchor bolt component is moved axially through the expansion sleeve component, the maximum interference area (M.I.A.) and maximum interference volume (M.I.V.) can be generated between the anchor bolt component and the expansion sleeve component in a controlled and predictable manner, as well as between the expansion sleeve component and the internal peripheral side wall portions of a concrete substrate or substructure can be generated so as to enhance pull-out resistance and reliability of the anchor assembly within the concrete substructure or substrate.

Abstract: A material testing machine is provided, in which a motor is used as a driving source of a loading mechanism, and the material testing machine can always perform a material test accurately, without requiring skilled operators, trial and error, or a longer time when setting control gains. A ratio K(t) of an inspection value F(t) of a control quantity to a displacement θ(t) of a motor 21 is calculated sequentially, and a value proportional to a value obtained by dividing a deviation {FD(t)−F(t)} by the calculated ratio K(t) is taken as a rotation angle command and supplied to a servo amplifier 36. The servo amplifier 36 supplies a current to the motor 21. Therefore, as the test proceeds, appropriate gains are automatically calculated and set, a gain setting operation before test is not necessary, and the material test can be always performed accurately.

Abstract: The invention provides a fatigue exciter for wind turbine blades. Wind turbine blades require excitation at or near their natural frequency to induce bending moments that simulate in service loadings and must be easily controllable and with the minimum of unnecessary added mass or force. The invention provides a device and a method by which force controlled feedback is used for finding an optimal excitation frequency. This force could be provided e.g. by a digital signal generator.

Abstract: A method and apparatus for testing shear stiffness in board is disclosed. The board sample (6) is placed into stationary jaw (2) and jaw (3) which is rigidly connected to inertial mass (7). The mass (7) is twisted around the sample axis with an initial twist chosen to ensure the sample is within the elastic region, and then allowed to freely oscillate. The oscillation frequency is then measured to evaluate the torsional stiffness of the sample.
