Challenge Problems
Push your limits with challenges.
Question 1
Given the following parameters for a fiber-reinforced concrete sample: fiber volume: 2%, aspect ratio: 50, and matrix composition: high-strength cement. Calculate the expected fracture energy increase compared to plain concrete, assuming plain concrete has a GF of 100 J/m².
💡 Hint: Consider how each factor contributes to toughness.
Question 2
Discuss how varying the fiber orientation in a concrete mix might affect its fracture energy and overall performance in structural applications.
💡 Hint: Think about how fibers might interact when they are oriented differently.
