Definition of Young's modulus in US English:

Young's modulus


  • A measure of elasticity, equal to the ratio of the stress acting on a substance to the strain produced.

    • ‘The comparably large decrease in the average Young's modulus could have been caused by floating of microvilli or lamellipodia, respectively.’
    • ‘The Young's modulus was obtained from a cylinder load test on the pile concrete.’
    • ‘The Young's modulus or stiffness of the stem and root material was calculated.’
    • ‘We observed a faster drug action at higher concentrations but only minor differences in the amount of decrease of the average Young's modulus.’
    • ‘Commercial nylon formulations often include plasticisers such as water, acids, alcohols and phenols, which reduce the yield stress and Young's modulus of the polymer, but increase the material toughness.’


Mid 19th century: named after T. Young (see Young, Thomas).
