deformation of a clamped circular plate

Submitted by winterfell99 on

Hi all, 

I need help to calculate the deformation of a circular plate(d=200mm and t=10mm) with a hole (d=20mm and t=5mm) at a center. The plate is clamped at its edge and subjected to 275KPa uniformly distributed load at the face without the hole.

I want to study the variation of maximum deformation with the  varying depth of the central hole. Any ideas on how I should approach this problem?

 

Analysis of microstructural induced enhancement of electromechanical coupling in soft dielectrics

Submitted by Stephan Rudykh on

Electroactive soft elastomers require huge electric field for a meaningful actuation. We demonstrate, by means of numerical simulation, that this can be dramatically reduced and large deformations can be achieved with suitably designed heterogeneous actuators. The mechanism by which the enhancement is attained is illustrated with the aid of both idealized and periodic models.
