WebFrom the stress–strain curves, it was found that all of the SN starch hydrogels were soft and flexible. To compare the effects of crosslinking time and GA contents of the mechanical properties of the SN hydrogels, their compressive strength, compressive modulus, and toughness were then plotted against crosslinking time, as illustrated in Figure 7 . WebThe proportional limit is defined as the highest stress at which stress and strain are directly proportional so that the stress-strain graph is a straight line such that the gradient is equal to the elastic modulus of the material. … the beach movie poster
