Sign of principal stress (S1) : tension or compression

[sev]

Hello,

I meshed a plate of glass with shells. Ansys gives me a picture of results (principal stress), with positive and negative values. Stupid question : positive is tension or compression ?

Thanks a lot

Hi,

Why don't you plot the principal stress as vectors. The arows of the vectors tells you about the type of stress (compression or tension).

PS: I suppose, positive must be tension...
