A neutron image plate (NIP) was used in this experiment to obtain neutron diffraction rings of polycrystalline steel specimen. The diffraction data were stored on a NIP and were converted to digital image data. Strains were obtained from these data and were analyzed to determine stress using the cosα method. Though these stresses were different from applied stresses, they increased in proportion to applied stresses. Namely, the differences between measured and applied stresses were almost constant during loading. Based on these experimental results, two practical methods were proposed for determining exact stress using a NIP. The stresses obtained using one of these methods showed good agreement with applied stresses. From these results, it is concluded that we can obtain mean stress in materials using neutron diffraction technique with an area detector., 金沢大学人間社会研究域人間科学系}, pages = {1711--1716}, title = {中性子応力測定へのエリアディテクタの適用に関する基礎的研究}, volume = {69}, year = {2003} }
