Hello,
I recently came across a website supplying Flat Washers made of Spring Steel. I am wondering what is the advantage of using a Spring Steel Flat Washer over regular Low Carbon Flat Washer.
By using spring steel flat washer can we eliminate the need of spring washer??
I searched the site...
Thank you hendersdc... once I change the weight of the body the deflections match. Now I can confirm the theoretical deflection of the plate for the given youngs modulus....
Thanks to you all guys....

I tried energy conservation equation as suggested by pperlich and tried Roark's as suggested by drawoh & hendersdc. There is big difference in answers. Plese see attached. I don't know where I am going wrong.... any...
Thank you very much drawoh and pperlich for showing me some direction. Can I use Roark's for plastics also? I always used it for metals before (this is my first time working with plastics).
Hello group,
I am trying to calculate the thickness of FRP plate (11"x11" - fixed all four sides) to sustain an impact with 2" metal ball hitting at 75 feet/sec. Any help pointing in the right direction is greatly appreciated. Any source/text book/web site to look for the formula or any equation...
@ 3DDave & tbuelna– I agree, it depends on the geometry. If we have any thickness or size limitations then we could justify it by making it bigger or thicker and use less grade material, but we do not.
@CoryPad – I am aware of different options of A710 and for any option 65ksi is min. I don’t...
@racookpe1978 – Customer specs is ASTM A-710 material, which is not a very common structural steel so has to be a special order from the mill and is approx..$82 psf and min order is 8’X20’.
@3DDave – for A710 yield is 65ksi and elongation is 20%; for A572-50 yield strength is 50ksi and...
Sorry my bad, should have made it clear.
It is a collision post for railroad maintenance of way equipment. Two posts are built into front of the car body so posts absorb most of the energy due to collision with other rail vehicles. The energy is the mechanical energy due to collision.
Thank...
Hello Group,
Can anyone help me how to calculate the energy absorbing property of a metal?? Because I am working on designing a steel structure and the customer requirements are
“…… structure shall be constructed of nickel-copper-chromium-molybdenum-columbium steel per ASTM Specification...
