    Material Effects on Tangent Modulus of Steel Square Hollow Section by Seyed Mohammad Reza Mortazavi, Milad Shakiba, Behrouz Zaeimdar

    Published 2023-05-01
    “…The kind of mild steel, the Bauschinger effect because of strain reversal and strain ageing are indicated to affect significantly the tangent modulus of elasticity. Stub column specimens made from a material that has been pre-stretched in tension have a significantly lower tangent modulus of elasticity than those specimens made from as-received material; the reduction is caused by the Bauschinger effect and a resulting reduction in tangent modulus and yield strength. …”
