Beam/plate on elastic foundation..?

cabellos6

As part of my project (designing an artificial spinal disc) I have to design the enplate pieces which will attach to the bone.

I am familiar with beam theory with regards to simple supports or cantilever beams but i have not yet studied beams on elastic foundation. I would be extremely greatful if someone could help me with this. I believe the endplate (shown in the link below) is similar to a beam/plate on elastic foundation when under a compressive load of 2000N.

I want to find the maximum bending stress due to this load but do not know how?

Thankyou.

Rather than rehash everything, I have a chapter of my Advanced Mechanics of Materials book by Cook and Young that covers this topic. I scanned it in, but it is about 100 k over the attachment limit. I'll have to see if there is another way to post it. I'll be right back. In the mean time, do a search for beams on Winkler foundations.

Here is a link to a website that can help http://www.me.ust.hk/~meqpsun/Notes/Chapter4(202).PDF

and some samples here

I cannot see your image very well, could you attach it or something?.

I guess I don't need to worry now. The links Cyclovenom posted are out of the same book.
