摘要： A method and system for measuring and determining the full-field spatial distributions of strain tensor field components in a two or three-dimensional space, as a consequence of deformation under generalized loading conditions. One or more digital cameras may be used to acquire successive images of a deforming body with optically distinctive features on its surface. A method for determining the location of characteristic points of the surface features and another one for tracking these points as deformation occurs. Elongations between neighboring points on the vicinity of a location of interest are computed. The elongation between points is calculated even though discontinuities may exist between them. Strain tensor fields are directly calculated as a tensor approximation from these elongations without determining or using the displacement vector distributions.

摘要： A method for detecting mechanical features of a material, in particular a metal material, provides a preliminary step where a database is created containing a finite number of reference curves (P,h) (52). Such curves are obtained using a finite elements analysis and reproduce the trend of the applied force (P) responsive to the penetration depth (h) during an indentation test. The reference curves (P,h) are obtained for a determined number of different materials having a known elastic modulus E, and values of yield stress (σsn) and strain-hardening coefficient (n) comprised within determined ranges. The tested sample is then arranged at an indenter, for example a ball indenter (52), for being subject to an indentation test. This is started to cause a graduated penetration of the indenter in the material subject to analysis (53). During the indentation test the penetration depth (h) responsive to the penetration force (P) are measured, and a succession of measured couples (P,h) (54) is then recorded. Such couples of determined values (P,h) are then computed (55), in order to extrapolate from the database at least one reference curve (P,h), for example by a least squares method (56).

摘要： A method for calculating a fatigue usage factor of a component in a nuclear reactor includes determining a flow scaling factor for each stress component of a stress cycle, applying the flow scaling factor to rapid cycling stress conditions, and performing a fatique evaluation by calculating a fatigue usage factor using the flow scaling factor. The flow scaling factor is a ratio of a temperature fluctuation ratio at a first reactor operating condition divided by a temperature fluctuation ratio at a second reactor operating condition. The temperature fluctuation ratio is defined as a ratio of the metal temperature range over the fluid temperature range.

摘要： A fatigue safety factor testing apparatus includes a FEM calculating section, a normalized stress calculating section and a fatigue safety factor calculating section. The FEM calculating section carries out a FEM calculation to meshes of a part to calculate a stress of each of the meshes of the part. The normalized stress calculating section calculates a normalized stress of a stress applied to each of the meshes with respect to a fatigue limit as a function of a temperature and material of each of the meshes.
