Dear All,

cloud any one help me, in App.P L/2a=1.0 and L/2a=1.5 if the values between 1.0 and 1.5 which one will be choose or can we choose the value L/2a 1.0=<1.25 and 1.5>1.25.

thanks in advance waiting for response.

Interpolation between 1.0 and 1.5 is allowed.

Thanks for your response.

how we can take effect the interpolation from the given chart of stiffness coefficient API provide only L/2a=1.0 and L/2a=1.5 charts it is very difficult to interpolate between the charts(manually without using software). can we assume upto 1.25 value chart L/2a=1.0 shall be use and above 1.25 value chart L/2a=1.5 shall be use.

You're correct, it is tedious. That is why I suggest you acquire our TANK software.
