Determining True and Apparent Modulus of Elasticity

Wed, 10 Jan 2007 10:19:00 -0700

The bending stiffness of a structural member is the capacity to resist deflection and is represented in equations as EI. The E is the modulus of elasticity of the material making up the structural member and the I is the moment of inertia of the cross section of the structural member.

When determining true (Shear-Free) and apparent modulus of elasticity, what are the differences in the test methods used? And what do the results mean to an engineer? [More]
