Failure of piping and components due to large-scale yielding crack propagation under cyclic thermal loading is of utmost concern.
Temperature and pressure data from a CFD simulation will be used as load input in a FEM model.
The goal of the FEM model is to analyze the magnitude of thermal stresses, including their cycles and sequences, which occur at mixing points due to temperature changes and pressure load.
The FEM simulation will give indication on the major cause of failure in components with mixing points; namely, whether it is due to large scale yielding load conditions or environmental conditions.
The actual damage simulations for fatigue crack initiation and fatigue crack propagation are stand-alone post processing tasks which are well suited for SNAC allocations.
These are Python, which is adapted to the PDC processors.
These FEM simulations are time-consuming.
