TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1985 軸対称三次元残留応力測定法としてSachs法がある. この方法は, 計測ひずみに誤差が混入すると誤差が拡大し, 残留応力の測定精度が極端に低下する. これに対し, 新しく固有ひずみを媒介とする軸対称三次元残留応力測定理論を提案し, 具体的な測定方法と手順およびSachs法の問題点が解決されることを示した. また, 軸材の焼入れにより生じた三次元残留応力を実測し, 固有ひずみを媒介とする新しい測定法の有用性と実用性を示す.

The influence of heating sequence on deformation of steel plate in induction heating process
Xibei Gongye Daxue XuebaoThe line heating formation of a complex curved plate needs multiple heating lines. Heating sequence is an important factor of influence on the formation to obtain the curved surface plate of a particular shape. The paper uses the elastic-plastic inherent

Journal of Low Frequency Noise, Vibration and Active Control, 2019 A high-speed reciprocating operating mechanism with fast running and frequent stopping produces a certain vibration due to inertia. The inherent vibration of this mechanism becomes a key factor affecting positioning accuracy and time.

Effect of intermediate principal stress on the stability of slopes [PDF]
Archives of Civil EngineeringThe intermediate principal stress (σ2 ) effect is a mechanical property inherent in many rock and soil materials. However, the effect of σ2 is often ignored in slope stability analyses, and its impact on slope stability is seldom investigated.

Self-Adaptive Moving Least Squares Measurement Based on Digital Image Correlation
OpticsDigital image correlation (DIC) is a non-contact measurement technique used to evaluate surface deformation of objects. Typically, pointwise moving least squares (PMLS) fitting is applied to process the noisy data from DIC to obtain an accurate strain ...

New Measuring Method of 3-Dimensional Residual Stresses Based on Theory of Inherent Strain
Journal of the Society of Naval Architects of Japan, 1979 The authors have already proposed the general principles in measurement of residual stresses. In this paper, the authors developed a new method for selection of observing positions of strains to ensure highly accurate measurement by using the theory of inherent strain, which is based on one of these principles.By this selection method, it is seen that ...
