The micropolar equations of motion are developed, in a very general form, for a
mixture of fluid and solid particles. The fluid is allowed to move differently than the solids,
and the solids are modeled as a micropolar continuum. That is, the solid particles have an
additional degree of freedom...
This report is one of a series issued in cooperation with the Army-Navy-Civil Committee on aircraft design criteria under the supervision of the aeronautical board. Information reviewed and reaffirmed 1962.
A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
