The effect of hydrogen embrittlement on the stress-strain curves measured at various strain rates is simulated by assuming that the hydrogen is generated in localised corrosion pits and subsequently diffuses into the bulk, thereby reducing the strain-to-failure of individual fibres. The stress-strain curves obtained from these simulations show the same strain rate effect as was experimentally observed.
