A cylinder is compressed by constant stress. The stress is displayed in the direction specified in the Set Coordinate System.
The deformation, the displacement distribution, and the stress distribution are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.

The contour indicates the Z normal stress. The unit is [Pa].
The maximum and minimum values for contour are set to 1 and -1 [MPa] respectively in the Graphics Setup dialog box.
To define a cross section, enter (0, 0, 2.5) for Point on Cutting Plane and (0, 0, -1) for Normal Vector of Cutting Plane in the Cross Section dialog box.
Also, select [Display the cross section and the surface simultaneously].
Under this setting, the normal vector matches the stress component in the direction. Therefore, the normal compressive stress is shown.
The normal compressive stress is 1 [MPa] as applied as the loading value.
To see the normal stress on the cross-section (Point on the cutting plane: X = 0, Y = 0, Z = 0, Normal vector: X = 1, y = 0, Z = 1) slanted by 45 degrees
or the shear stress along that cross-section, the coordinate system needs to be set.
Select [Local Coordinates] for the Coordinate System Type, and set up as follows.
Origin (X:0, Y:0, Z:2.5), X’ Vector (X:1, Y:0, Z:-1).
By selecting Z' normal stress, the stress component can be shown which is normal to the cross section slanted by 45 degrees.
The normal stress is -0.5[MPa].
The value is less than the applied load of -1MPa because it is in the slanted direction to the applied load direction.
By selecting Z'X' shear stress, the shear stress can be shown along the cross section slanted by 45 degrees.
The shear stress is 0.5[MPa].
In the diagram above, the red arrows indicate the force directions causing the shear deformation.
