'Pipe Joint' simulation project by rszoeke


I created a new simulation project called 'Pipe Joint':

In this project a static structural analysis of a pipe joint is demonstrated.

More of my public projects can be found here.


The CAD model is courtesy of GrabCAD member Greg Pavlik. The symmetry of the model was used to minimize the simulation domain. The resulting geometry was then meshed using the parametrized tetrahedralization operation, which was then uploaded to the SimScale platform. The mesh with second order elements is displayed in the figure below.

Three displacement constraints were used to generate the symmetry planes. Also all connections to the pipes were constrained and a pressure load of 5 bar was created on the inner surface of the pipe joint. After the simulation design a static structural analysis was carried out on an 8 core machine, which took only 4 minutes. In the picture below the von Mises stresses are shown under the prescribed load. The consistent gradient is only possible with second order elements and allow for a detailed assessment of the structure.


Can I know from the above result, what we can conclude?

Is there a critical failure in the center of the pipe joint, this needs to be taken care during design,?

Can anyone answer to this question?
