Equivalent elastic modulus
Equivalent elastic modulus
(OP)
Hi,
I have a steel plate coated with lead.
How can I find the equivalent modulus of the plate, if the steel and lead plate thickness are equal.
The plate is subjected to axial as well as bending loads.

This plate covers x-ray source. It is coated to avoid passage of x-rays.

RE: Equivalent elastic modulus
Axial - set the strains equal,
stress in stl = [Es/El]x Stress in lead
Bending - use equivalent cross section, equiv width of steel = [Es/El]*orig width.
maybe neglect lead altogether [since E~ 1/15 that of steel]
& just use steel thickness in calc's?
