Tensile Modulus By X-Ray Diffraction: Instrument and Method
Autor: P. G. Lenhert, W. W. Adams
The design and use of an automated device to measure the axial tensile modulus of high modulus fibers by following the change in the meridional X-ray spacings as a function of applied tension is reported. The device, which mounts on a Picker 4-circle
