Fracture toughness testing is critical to assess material resistance. Discover how nanoindentation can help testing it.

Thus, proximity to crack initiation or unstable crack growth is assessed by calculating the crack driving force and comparing it with the material fracture toughness. This presents a major difficulty ...

with nonlinear relationships between crack-tip geometry, fracture toughness, and fiber orientation. Based on the findings, the researchers designed a heterogeneous plywood system with enhanced ...
