having access to stress/strain curves and fatigue curves would be interesting to me and our customers. we get that call on support quite often.
the export option does sound intriguing. that option has been available for matweb for some time now but I haven't really seen it catch on. if there was some way to grab the material from directly inside of solidworks simulation, that would be the most helpful. kind of like how the online help takes you to the forum for additional info.
Yes, I am aware of the option offered by Matweb that you mention.
However, it seems that only individual parameters (such as yield strength and ultimate strength) and not whole stress-strain curves are available for export/import.
I have also noticed this lack of access to complete curves is the primary complaint from the users - at least this is the impression that I got from information gathered from different forums.
