A brittle sample of polystyrene behaves elastically in tension, until it breaks in two when extended 2.2%, under a load of 55MPa. What is the toughness of this sample?
i know i may use the stress strain curve to solve this problem? (Force vs elongation)... but how do i solve the toughness of the sample?© BrainMass Inc. brainmass.com September 25, 2018, 7:24 am ad1c9bdddf - https://brainmass.com/chemistry/materials-chemistry/tension-brittle-sample-polystyrene-30265
