I have a large polymer plate of 45cm x 120cm, with Young Modulus 0.8 GPa and I want to calculate the safe thickness (before fracture) of that plate on a middle line force across the width of the plate with magnitude of 0.6 kN.
The middle line force distribution is shown here: http://img819.imageshack.us/img819/7450/49266917.jpg [Broken]
The Attempt at a Solution
I use flexural modulus formula but i just noticed that flexural modulus is not the same with young modulus.
