Prediction and Experiment Comparisons for German Standard Problem 4A: Piping Response to Blowdown.

摘要

This report consists of comparisons of prediction and experiment for German Standard Problem 4a, a blowdown experiment involving structural dynamic response. The comparisons presented herein are of the time histories of displacement, bending stress, and bending axis angle. The reasons for error in the predictions are discussed. The structural model is improved to obtain a better match with the experimental natural frequencies.
