Autor: AS Kleinberg, RL Meltzer, JR Schroeder, B Benzing, MB Vieth, K Greene, MT Pravitz, K Hirano, H Kobayashi, H Nakazawa

Publikováno v: Journal of Testing and Evaluation. 13:356

This paper reports the summary of JIc test procedures based on an ultrasonic method proposed earlier. The single-specimen JIc measurements for low- and intermediate-strength, high-toughness materials show excellent agreement with those determined by

Comparison of Precision and Accuracy Estimates from State and Local Agency Air Monitoring Stations with Results of EPA's National Performance Audit Program

Autor: E.G. Evans, MB Vieth, WJ Mitchell, K Greene, JR Schroeder, R.C. Rhodes, MT Pravitz, J.C. Puzak, RL Meltzer, B Benzing, AS Kleinberg

Publikováno v: Journal of Testing and Evaluation. 13:374

Federal regulations require that state and local air monitoring agencies perform special checks to assess the precision and accuracy of their measurement systems and report the results to the Environmental Protection Agency (EPA) each calendar quarte

Nondestructive Evaluation of Bond Quality of Bimetallic Strips Using Acoustic Emission

Autor: AS Kleinberg, RL Meltzer, JR Schroeder, B Benzing, MB Vieth, K Greene, MT Pravitz, CRL Murthy, KK Brahma

Publikováno v: Journal of Testing and Evaluation. 13:371

Acoustic emission (AE) appears to hold good promise for nondestructive evaluation of bond strength of bimetallic strips in two ways: (1) as a quality control tool in batch sampling and (2) as a 100% inspection method. A program has been initiated at

Determination of Modulus of Rigidity by ASTM D 198 Flexural Methods

Autor: AS Kleinberg, RL Meltzer, JR Schroeder, B Benzing, MB Vieth, K Greene, MT Pravitz, DS Gromala

Publikováno v: Journal of Testing and Evaluation. 13:352

Traditional equations for determining shear modulus for beams are based on several simplifying assumptions. Although these assumptions are reasonably accurate for isotropic homogenous beams, they can introduce large errors when applied to beams of st

A Method for Determining the Effect of Fasteners on the Stiffness and Strength of Wood Drive-In-Rack Pallets

Autor: TJ Urbanik, RL Meltzer, JR Schroeder, MB Vieth, AS Kleinberg, MT Pravitz, K Greene, B Benzing

Publikováno v: Journal of Testing and Evaluation. 13:379

Wood pallets are increasingly stored in warehouses with drive-in or drive-through racks. A pallet needs adequate stiffness and strength to function safely under conditions where it spans the rack support rails. When the stringers run parallel to the

Test Method for Evaluation of Shear Modulus and Modulus of Elasticity of Laminated Anisotropic Composite Materials

Autor: AS Kleinberg, RL Meltzer, JR Schroeder, B Benzing, MB Vieth, K Greene, MT Pravitz, S Cheng

Publikováno v: Journal of Testing and Evaluation. 13:387

A test method for the determination of the shear modulus and the modulus of elasticity of laminated anisotropic composite materials is presented. Two tests are required. In one test, a ring is simply supported at two diametrically opposite supports a

Publikováno v: Journal of Testing and Evaluation. 13:329

Six materials, copper and copper alloys, have been subjected to long-term creep tests (30 000 h) per DIN 50 118 at a range of 100 to 250°C, except for aluminum bronze which was tested from 150 to 300°C. The following annealed materials were tested:
