T&R Report R-05: Feasibility of Measuring Strains Corresponding to Bending Moments with Several Inflection Points (1967)

Examination of the feasibility of measuring deviation in strain distribution from that predicted by simple beam theory in flange plating of a ship hull is performed on a modern sea-going bulk ore carrier. Bending moments resulting either from adding loads or from shifting loads are investigated. The corresponding primary stress distribution in the envelope plating is predicted by Schade's method. Remarkable and readily measurable strain deviation in the bottom plating is found in several cases.
