Gaussian charge optimisation confirms ridge scaling
¥Stretching
energy can be expressed as an integral of gaussian curvature
analogous to electrostatic energy.
¥A
stretching ridge has negative gaussian curvature.
¥It
must be compensated by an equal amount of positive gaussian curvature on
the adjacent flanks
¥Optimising
the width w of this ÒchargeÓ
distribution gives
¥w
~ X (X/h)-1/3 , confirming other methods.
