I have seen several statements in calculations that doubling a sole pad doubles the bending stress, trebling..trebles the bending stress so that allowable bending moment of a sole pad is stated as 0.468kNm for single, 0.936kNm for double & 1.404kNm for treble pads
Section modulus for a rectangular section is not directly proportional depth but depth^2 (since z=(bd^2)/6)
My question is - do any designers have any calculated proof to support some designers' assumptions that allowable bending moment doubles...trebles when used in a loosely layered configuration (i.e. not nailed, glued, banded).
