2 cards from this section. Quick, good the night before a test.
What does the Modulus of Elasticity tell us about concrete?
Think about how much the concrete will deform.
Define Poisson’s Ratio in your own words.
Focus on how concrete behaves in two directions when stress is applied.
What does the Modulus of Elasticity measure?
Consider what E refers to, related to deformation under load.
True or False: A higher Poisson’s Ratio means that lateral strain is significantly less than axial strain.
Think about the relationship between the two strains.
Given a concrete with a compressive strength of 30 MPa, calculate the Modulus of Elasticity. Discuss how this affects structural design.
Use the modulus formula and remember the significance of stiffness in design.
Discuss the implications of having a Poisson's ratio upper limit of 0.25 for a specific type of high-strength concrete.
Think about high strength influencing deformation.
