Inelastic response of a nuclear pipe elbow subjected to rupture forces
Description
The inelastic response of a nuclear pipe elbow subjected to rupture forces caused by a circumferential break in the pipe leading into the elbow is analyzed with a three-dimensional finite-element technique. A finite-element technique is presented which is capable of solving for the inelastic, large deformation dynamic response of three-dimensional solids. Results are obtained with and without strain rate effects included in the material properties. Different mesh spacings were used in different calculations to ascertain the accuracy of the calculation. The results were also compared with another investigator's results where beam elements were used to simulate the pipe. 14 refs
