Development of the Three-Dimensional SHAPS Code Capabilities for Application to LMFBR Piping Systems

摘要

The SHAPS code couples three-dimensional pipe elements and elbows with two-dimensional hydrodynamics in order to account for fluid-structure interaction, motion of fluid due to moving pipes, and deformation of the structure. Each pipe element is formulated with eight degrees of freedom per node to consider translation, rotation, and membrane bending and breathing modes of the structure in order to calculate the stresses arising from internal pressurization as well as the three-dimensional flexural motion of the piping system.
