Compare the Young's modulus E∗ of two open-cell foams. Which Young's modulus is higher? Recall that C1=1.
1. polystyrene: (Es∼3.5GPa), ρ∗/ρs=0.3
2. Al 7075-T651: (Es∼72GPa), ρ∗/ρs=0.1
E∗PS (in GPa):
E∗Al (in GPa):
Select the correct answer:
Polystyrene has a higher Young's modulus
Al 7075-T651 has a higher Young's modulus
1 answer
Al 7075-T651 has a higher Young's modulus
