Fundamental behavior of paper in tensile loading in key to understanding the quality of paper. The stress strain plot of paper is a model of the stress-strain tensile behavior of machine-made paper. The graph shown represents the behavior of two strips cut from the same sheet of paper in different directions: machine direction (MD--the direction in which the paper moves during .force) and tear strength (out-of-plane force). This arises from the longer fibers presenting more bonding opportunities/fiber. The relation holds over a range of sheet densities as shown in Figures 2. Figure 2: Increasing avg. fiber length from 1.47 to 2.70 mm increases tensile strength, at fixed bulk, for softwood Kraft pulp.
