Linearize Stress PropertyManager

Stress linearization separates bending and membrane stresses for solid mesh models. For shells, you can plot and list membrane and bending stresses separately.

To open the Linearize Stress PropertyManager, run a pressure vessel study and define a planar sectional stress plot. Right-click the stress plot and select Linearize.

Options

	Locations	Select two locations on the model's section that define the line along which the stresses are reported. The two locations must belong to different elements of the same body. Reference points are not valid selections for a stress linearization path.
	Number of intermediate points	Defines the resolution of the graph along the line. The software interpolates stress between the first and last point to find stress results at intermediate points. All locations along the stress linearization path (including intermediate points) must belong to the same body.
	Calculate	Calculates the membrane and bending stresses at the selected locations and intermediate points. Stress results at the two selected points are listed in the Global coordinate system. You can view the full range of results, including intermediate points, using Report Options described below.

	Summary of Results	The table lists the linearized stresses (membrane, bending, and membrane + bending) and the peak stresses for the six stress components, von Mises, and stress intensity (Tresca stress). The software reports the six stress components (stress tensor) at each node based on the local coordinate system defined by the Stress Classification Line (SCL). The SCL line is oriented normal to the midsurface of the wall thickness. N: Normal vector or Meridional T: Tangential vector from the inner to the outer wall H: Hoop vector normal to the section plane See also help topic: Linearizing Stress Results (Pressure Vessel Studies)
	Save As Sensor	Saves the coordinates of the two location points as sensors.
	Save	Saves the results to an Excel .csv or text .txt file. The .csv file contains all the stress components in the Global coordinate system and in the SCL coordinate system.
	Plot	Creates plots of the six stress components that show the stress variation across the wall thickness.
	Save the data and show in Report	Saves and shows the results in a report.
