Urgent How to find the point where Maximum Curvature occurs on graph?

    Urgent!!How to find the point where Maximum Curvature occurs on graph?

    1. The problem statement, all variables and given/known data
    The graph(2D) is plotted from experimental data, not from a given equation and within certain limit. I want to know the x&y coordinate where the maximum curvature occur via software means, not manually. FYI, for those with civil&geotechnical engineering background, the graph i am plotting is about consolidation topic of soil mechanics subject, which is the void ratio vs effective stress curve. I want to get the preconsolidation value from the graph plotted.

    p.s. the attached file is rough idea of what i mean.

    From the tone of this, I suspect that you are to determine the point of maximum curvature by looking at the graph and deciding where it appears to "curve" most!

    yes, do u know any software that can find the point?

    lol,no offense i aint that advanced to get the maximum curvature by hand calculation, lol, that's why i need a software, if not, imma get the point via naked point instead

    I think you mean "naked eye", not "naked point". Anyway, that is what you need to do. Also: please avoid 'text-speak' in this Forum; take the trouble to say 'I' instead of 'i' and 'you' instead of 'u', etc.
