Layman's Course in Mech Eng: Stiffness 101

[shadowfist]

Wow I did not realize the ISC has done so much research .

I was hoping there would be another spike after 50

That chart is a little dated of course 2006; there might be some hope yet

the chart of course does not reflect materials that have had contact with non-naturally occurring substances. because obviously those materials would have a virtually infinite situation count.

Nice post! I'm learning this now in my strength of materials course. Of course, that slideshow is miles better than my professor giving a summary of what the book says without relating to engineering practices.

What no Viagra jokes .

Glad it helped. A little practical application can be very motivating to delving deeper and developing a fundamental understanding of these principles.

With some of the visualization tool you have today, it is certainly easier to grasp some of this stuff than when I was going to school.

why yes, yes i do.

Great graph, but does it tell the whole story? Were alcohol percentages factored into the various occasions when stiffness occurred? It is a well known that moderate levels of alcohol can be successfully used as a case hardening tool. In materials aged from 20-35 years, an early dilution of the alcohol percentage results in the stiffness faze known as, the "Dawn Breaker".
However, should alcohol percentages be raised alarmingly, there is a reversion of hardness.

The fact that stiffness declines more rapidly as material ages is of concern. When material reaches 60+, the researchers appear to have dozed off, or was it the material that did that?

Did you go to school. We were so poor . . .

Since my Dad was 60 when I was born and my Mom had a miscarriage before me, I think the graph is a little off.

Did you get to go to school. We were so poor . . .

I'm so poor...... I can't even pay attention

That's a shame Dave..........I've heard she's good value!
