We would like to do an FEA analysis on a simple foam impact test.
The supplier has provided us with the following properties:
Polyurethane
* Density
* Indentation Load Deflection
(25% ILD @ 4")
* Tensile Strength
* Tear (lbs per inch)
* Elongation
Polyethylene
* Compressive Strength...
Are there any sheet metal gurus out there that could recommend how to form a C-Channel type arm rest with the front two-thirds of the channel angled downward approximately 8 Degs. (Without any secondary welding operations.)
We're designing a cast part that will be manufactured in China. We've spec'd a min. yield strength and they're telling us that they'll be using a material called ZG25.
I've searched matweb and everywhere on the net and can't seem to find material properties (yield strength, modulous of elast...
We're working on a project with a 1/2" square torsion rod that is being used to act as a variable spring by moving a slider with a square hole in it up and down the length of the bar to change the effective length.
We're needing a minimum yield strength of 260 ksi for our application. Can...
Can anyone provide any advice on a problem we're having with heat treating a 1/2" square 4140 rod.
We're shooting for a yield strength of 210 ksi. The first batch came back great, no problems.
The second batch, all but 2 of 15 came back terribly warped and with many cracks along the length of...
