Poisson's Ratio - Volumetric Change

Volumetric Change

The relative change of volume ΔV/V of a cube due to the stretch of the material can now be calculated. Using and :

Using the above derived relationship between and :

and for very small values of and, the first-order approximation yields:

Famous quotes containing the word change:

    The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.
    Willard Van Orman Quine (b. 1908)
