Dear all I need to validate a model developed by me. The model gives the influence of residual stress on deflection and pull-in for a square diaphragm. I have found a lot of research papers giving the experimental data for beams but i couldn't get the ones for square diaphragm. If anyone could suggest me few research papers giving experimental results of bending of square diaphragm under influence of residual stress as well as pull-in voltage to or send pdf for the same, i shall be grateful Anurekha
