  title={Admissible modeling errors or modeling simplifications},
  author={J. Douglas Reid},
Abstract Discovering modeling errors on large finite element models is complex and can often go unnoticed, particularly once good “correlation” is achieved. The signs of trouble and/or inaccuracies need to be recognized and, at the very least, the effects of system simplifications on a model's accuracy need to be known. One danger in using simplified models occurs when the models, which have been correlated to test results, are used for predictive work. When predictive work begins, it is… CONTINUE READING
