Hello, thanks for your prompt attention.
I have taken your N data and want to calculate N_membrane.
I am following below procedure as per formula screenshot given in above discussion.
for
i=0 , dx/dt=1/2n & i=n , dx/dt=1/n for membrane stress
here n =11
so,
N0 = -833.28 = -833.28/2x11 =...
i am new to PV design.
I have confusion in calculating membrane, bending stress & principal stress from excel file you have give.
will you please show single calculation. thankyou in advance.
