WebMaterials sometimes display brittleness which precludes their use in a given design. Brittleness is characterized by fracturing with low energy under impact. ... The fracture … WebAnswer • For increasing strain rates, the stress-strain curve would be expected to shift from 3 to 1. • As the strain rate increases, the polymer chains are given less time to orient themselves along the axis of loading. Thus, at higher strain rates, the sample behaves in an increasingly brittle manner and with a higher strength.
