Residual Stress Analysis

High-energy X-rays with high intensity have made the production of two or threedimensional residual stress maps feasible, which are increasingly being employed by engineers. Such experimental results are needed for the evaluation of the predictions of finite element (FE) simulations. Stress maps can easily consist of 104– 105 measurement points; in situ experiments, e.g. under external load, increase the amount of data yet further. However, an upper limit for the data rate is imposed by the maximum speed for shifting samples through the beam. Estimation gives maximum data rates of about 580 GB/d.
