    Description

    Poor formation in paper, as denoted by large local variation of mass, tends to reduce maximum tensile strength but has not been well characterized. The effect of grammage variation on tensile strength was studied by introducing carefully placed holes in tensile specimens made of three different paper materials. Previous researchers demonstrated that the point-stress criterion (PSC) accurately predicts failure for paper specimens containing a single hole. Results of comparing the PSC for multiple holes in paper indicated the PSC provided a conservative strength estimate for specimens with multiple holes.
