# Deformation of flat plate with uniform thickness

## Deformation of flat plate with uniform thickness

(OP)
Hi

I'm looking for a formula that will yield the maximum stress and deformation of a flat plate under uniform load.  I understand from a previous post that Pounder's plate theory is the way to go, but I do not have a copy of the text they reference.  Is it available on the net?

For circular and annular plates you'll find it in the site below (rectangular plates to come...).

Thank you.  Unfortunately I am looking for the rectangular plate formula.

### RE: Deformation of flat plate with uniform thickness

Try "Roark's Formulas for Stress & Strain" - McGraw-Hill.

### RE: Deformation of flat plate with uniform thickness

Two sources that I can think of:

- Roark's Book chapter 10  Table 26
- Mark's Standard Handbook for Mechanical Engineers 1978 edition page 5-52 & 5-53

If you don't have these resources post you details and I am sure someone will post an answer.  Rich

### RE: Deformation of flat plate with uniform thickness

I think there is a Mathcad 2000 Pro sheet downloadable from the Collaboratory site. I can send it (Plate10b.mcd) to you, of if you can't make it operative, a .doc file to see the formulation at least. Post if so an e-mail address.

Thanks everyone, I have found a copy of the info and it is exactly what I needed.

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook â€“ How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final productâ€™s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded \$1 trillion dollars for the first time. Download Now
