A loop test for bending length and rigidity

Abstract

The theory of a proposed new test for bending length is presented. It consists in laying down on a horizontal surface a strip of the material in the form of a loop. The bending length is then proportional to the height of the loop with a factor of proportionality of 1·103. This factor has been found by numerical integration of the equations of equilibrium of a strip bending under its own weight.
