Analysts will sometimes exclude a layer of elements on either side of a bonded contact because the bonded contact is an approximation which can create a high stress artifact. You can create a Named Selection of Elements using the Worksheet to select elements by Z coordinate. Make several rows so that a layer of elements on either side of the bonded contact are excluded from the selection. Use this Named Selection to plot the stress.
Stress results on element shapes with low quality can have a high stress artifact. Geometry improvements can enable better element shapes. Virtual Topology can enable better element shapes. But if you don't have geometry and the mesh is created in an external program, then you must fix the shape there. Generally smaller element sizes are going to create higher quality element shapes.
If you can't get element shapes of a sufficiently high quality, then you can create a Named Selection to exclude elements of low quality from a Stress result plot.
