    How To Calculate Average Yield Strength

    Thanks for that mrfailure. All along I was assuming that "minimum yield strength" meant the point at which the yield curve begins, "maximum" would be at the end of the curve, and "average" would then lie in between. It sounds like from what you're saying that "minimum" or "maximum" yield...

    How To Calculate Average Yield Strength

    OGmetEng, I agree that there is no such thing as "average yield strength" . . . published. The fact that someone has taken the trouble to include it into their formula must mean, therefore, that an average yield strength value can be obtained. And I would, therefore, agree with mrfailure that...

    How To Calculate Average Yield Strength

    My goal was to determine a somewhat accurate value for "average yield strength" which would insure that my "bottoming" force calculations were not out in space somewhere. As long as the "bottoming" force formula results were within ± a few tons the numbers would be suitable from my practicle...

    How To Calculate Average Yield Strength

    To be honest, I'm not sure what the definition of "average yield strength" is. That was the term given in the formulae I posted. And those formulae apply only to the calculation of "bottoming" force. I'm assuming that there is a low and high point in the yield curve and the average would be...

    How To Calculate Average Yield Strength

    OGMetEngr, I have not defined "average yield strength" as I have been searching for a long time for a definition and have not been able to find one. I'm assumming that "average" would be in the context of the mean yield lying between the low and high points of the yield curve. But since I'm...

    How To Calculate Average Yield Strength

    I've searched hi and lo for a definition of "average yield strength" and have come up empty. I utilize a particular formula which determines the bottoming force of a forming operation in metal press stamping. Bottoming force is the force exerted when a forming operation is at the bottom of the...

    Sheet and Coil Stock Material Data

    Thanks again, Cory. Would you be able to suggest sources for obtaining standards? And possibly suggesting which standards I would need? I have a feeling that these will be expensive? Thanks, Pete Western Design Services Co. Ltd. Bangkok, Thailand Western Design Services Chicago, Illinois USA

    Sheet and Coil Stock Material Data

    Thanks for the reply, Cory. I do use MatWeb but my problem here is pinpointing specific material from the information I am supplied with by my customers; material specifications usually called out in the piece part print. For instance, 070 XLF HSLA, or CEMS A-6 Grade 1. For these two material...

    Sheet and Coil Stock Material Data

    Hi, Not sure if I'm placing this post in the appropriate forum so if there's a more suitable forum please advise. I'm looking for material data on a wide variety of materials used in metal stampings; stainless steels, beryllium copper, Series 1000 cold rolled steel, galvanized, bronze, phospur...
