Paper will introduce a novel active piezoelectric structural ?ber that can be laid up in a composite material to perform sensing and actuation, in addition to providing load bearing functionality.
Find a code in Matlab or Mathematica to obtain fig 1 and 2 with different variables.
Hint, use equation 9 and 10 to get the right code.
You should write a code just not anything else. this order required one how has experience in Matlab or Mathematica programming

The electro-mechanical coupling of a piezoelectric structural fiber with a piezoelectric coating is calculated and it is denoted as d31 fiber. For different values of aspect ratio low modules of carbon fiber and SIC fiber is obtained. To predict the coupling of multiple active fibers the rule of mixtures are applied by taking the piezoelectric shell as an inter phase layer which is denoted as d31Lam. volume fraction of the active fiber for various fiber aspect ratios are calculated.d31Lam/d31 is obtained for different values of carbon fiber volume fraction
Very professional and also went above and beyond my expectations. By completing the assignment within such a short time frame and getting it back to me very early. And except just a small correction everything was fantastic. thanks for the same.
Data is required to solve the problem. you can not get fig,5 and 6 with Matlab alone, you have to do FEA analysis also. Every material has different properties. you need to specify. you have to specify what is the range of V and r ? Required data or below properties of material Yp is the longitudinal modulus of elasticity of the piezoelectric shell, r is the piezoelectric shell longitudinal stress, e is the piezoelectric shell longitudinal strain, and d31 is the piezoelectric coupling. your right I need some time to obtain all data that require to solve it. just give me 3 days to get that Below are the material properties you need it d31=-320*10.^(-12); % piezoelectric coefficient (C/N) Y_p=62; % Longitudinal modulus of the piezoceramic (GPa) Y_f_c=250; % Longitudinal modulus of the carbon fiber (GPa) Y_f_sic=380; % Longitudinal modulus of the SiC fiber (GPa) Y_matrix=4; % Longitudinal modulus of matrix (GPa) vp, vf, d31 eff. d13eff = -d31/ln [(1-a)(1/a-0,5)] where a = t/r0 a = 0.1 = 0.001= 0.9 t = thickness of piezo r0= radius of (carbon + piezo) a= aspect ratio vp+vf+vm= 1 vp+vf= 0.1 = 0.001= 0.9 note that d31for fiber = d31 multi
