Hi All

I am new to optimization , and I would like to know , how is it possible to optimize The ABD matrix of a one layer orthotropic plate using Fmincon or so ?

I know there is sizing possible , but I would like to optimize the whole ABD Matrix , shall you guide me how to ?

So what I have got is six diagrams of stiffness matrix elements , which each one , increase or decrease , mostly exponentialy, with one parameter , like maximum deflection , how do I contain all of these data together in a MATLAB optimizer command ?

thank you very much

I don't know what an ABD matrix is or what an orthotropic place is. But to learn about Optimization Toolbox, I suggest that you work through the Getting Started example. Then take a look at the steps in Optimization Problem Setup, especially Choose a Solver, Write Objective Function, and Write Constraints.
