The present invention relates to test weights for testing the load capacity of a crane. More specifically, the present invention provides a novel system and approach simple and efficient crane load testing using solid weights. Previous methods of testing crane load capacity often require significant time to configure and reconfigure the apparatus. The system of the present invention increases efficiency by significantly reducing this configuration time. The system comprises a plurality of stackable test weights, and a lifting fixture specifically designed for the system. A cantilever structure located on two opposing sides of the test weight enables the lifting fixture to first be quickly secured underneath of said structure, and then lift that particular unit as well as any units surmounting that unit. A novel block lock system integrated into each weight unit enables self-alignment and securing of each weight as it is placed onto the weight stack.

A testing instrument and method for measuring the intrinsic strength of polymeric materials via cutting includes a pair of mechanical clamps connected at a base to low-friction hinges. The clamps are configured to secure the elongate edges of a polymer specimen, and to periodically load the specimen to a predetermined strain. The load on the specimen while strained is measured with an opening force load sensor. While in the strained condition, the specimen is cut with a highly sharpened blade, and the cutting force also measured by a cutting force load sensor. A cutting energy curve may be plotted from these measurements, from which a cutting energy can further be derived. The cutting energy is compared to a control material with a known cutting energy and intrinsic strength. The cutting energy and intrinsic strength being linearly proportional, the cutting energy for the specimen may thereby be determined.

A method of detecting internal defects in composites or other multilayer materials includes generating a wavefield on a surface of the material. Wavefield data is collected from the wavefield on the surface, and the measured wavefield data is processed to provide measured energy data. The method may include generating simulated or predicted energy data for the multilayer material that is compared to the simulated energy data to determine if the multilayer material has internal defects or damage below the surface. The method can be utilized to detect and/or quantify damage or other defects that are “hidden” by damage that is closer to the surface of the material. 1. A method of detecting hidden internal defects in a component comprising a multilayer material from a single side of a surface of the component , the method comprising:connecting at least one transducer to a component comprising a multilayer material having a surface;actuating the transducer to generate a wavefield on the surface of the multilayer material such that energy is trapped near the surface due to a first defect below the surface;collecting wavefield data from the wavefield on the surface of the multilayer material;processing the wavefield data to provide measured energy data;comparing the measured energy data to the known energy data for a multilayer material having known hidden internal defects to determine if the multilayer material has hidden internal defects that are further from the surface than the first defect and overlap the first defect and/or to quantify such hidden internal defects.2.
