Experience in Gasket testing
Hi,
Do any one in this forum has experience in simulation of gasket? I need to know about two things.
-
Whether the pressure-closure curve is same for both bead and non-bead section in a gasket? -
What is the physical importance of Transverse shear stress (TSS) value? How to obtain this?
Regards,

Hi Benjamin,
I have done many gasket simulations over the past 18 years. In the days when no gasket elements where available I have written my own solver for this type of problem. But this is another story.
I assume you are talking about a sheet metal gasket with one or more layers. In this case the beaded section has always a different loading and unloading behaviour. In addition to that you have typically different beads in complex gasket designs. For instance, a cylinder head gasket has different beads for the combustion chamber and the sealing of oil and/or water. This means you have to use different material properties.
According to my experience the physical importance of the transverse shear stress is quite low. It is common to substitute the presence of many layers with one appropriate load deflection curve. This would mean the transverse shear stiffness for this simplified model is something between the layer stiffness itself and the stiffness caused by friction between the layers. And this is very hard to determine.
