摘要

The effect of reinforced cutouts in a plane sheet under various loading conditionsis considered, and a number of experimental results are given for circular andelliptical cutouts with a uniform plate reinforcement, subjected to various systemsof biaxial tension and pure shear.These experiments were conducted using a plane loading frame, and theresults are compared with the theoretical plane stress solution. For the circularcutout the effect of neglecting the bending stiffness of the reinforcement is considered.Some additional experiments were carried oUt on a 60 in. diameter pressurisedcylinder containing an elliptical hole reinforced according •to Mansfield's neutralhole theory. The strains in the sheet in the region of the neutral hole are .comparedwith the corresponding strains in the uncut sheet.The experimental results obtained generally show a good agreement with thetheory.
