Typical values of Yield Strength, Ultimate
Strength
NOT FOR DESIGN. Consult
design manuals and material manufacturers for appropriate values. There
is a large range of properties, even within the "same material"
(e.g., steel) depending upon manufacturing processess, etc. Where
no Yield Strength is given, the material has no discernable SY
- either very close to Su (e.g., brittle materials such glass
and tungston), or the s-e curve is "sloppy" (plastics).
