piezoelectric composite plate analysis using ansys

piezoelectric composite plate analysis using ansys

piezoelectric composite plate analysis using ansys

(OP)
hi everyone,
please help me in finding the displacements due to the application of voltage on piezo layer.
the lay up consists of two piezo layers- one at top and the other at bottom.in between graphite/epoxy layer.
which element should i consider in ansys. can anyone guide me step by step procedure as iam new to it.

RE: piezoelectric composite plate analysis using ansys

I believe the elements you want to use would be either SOLID5,SOLID98, or PLANE13. These elements have voltage and displacement degrees of freedom. For the graphite/epoxy layers use whatever structural elements you would normally use. For the piezoelectric elements you need to define the material matrix using a data table. I beleive that the piezo elements can be driven with a voltage or a current. I would suggest that you consult the element reference library for more information.

hi spongebob007,
thanks for ur valuable suggestion. i tried solid 5 for piezoelectric layer and solid 45 for graphite/epoxy layer. iam not getting the exact results which i want. what i made is as follows:
1.given preferences-structural,electric
2.added elements solid5 and solid45
3. given material properties for both elements,
4.in section i considered shell and gave three layers,mat no, thickness, orientations
5. in modelling i created the required volumes.
6.then i glued the three volumes.
7 meshed total volume.
8. applied constraints and applied electrical load of 100 volts on top piezo layer
but iam getting a deflection value of around 0.08e-18 please have a look at the attachment and suggest me whether my approch is right or not.

RE: piezoelectric composite plate analysis using ansys

I can't open the file you attached. It's been a while since I have done this so I don't remember all the details. You might want to try applying a load of 0 volts on the bottom of the piezo layer. You might also want to take a look at how you input the values of the piezoelectric matrix for the solid5 elements.

how can i apply load in the form of (10 sin pi x/a sin pi y/b) in the static analysis in ansys, where a & b are dimensions of plate, x=a/2,y=b/2

(OP)
can anybody tell me how to model piezoelectric plate in ansys? the plate consists of two layers and it is simply supported. which element should i consider? i need to find nodal deflections under the application of voltage
