How Material Heterogeneity Creates Rough Fractures

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]
