## Abstract

Fracture mechanics has been studied for over a century, yet the rapid and accurate determination of fracture toughness through non-destructive methods remains a significant challenge. Current American Society for Testing and Materials (ASTM) standards rely on destructive testing of large specimens, such as compact tension samples with pre-cracked tips. These tests are costly, time-consuming, and often impractical for in-service infrastructure like pipelines, pressure vessels, and aircraft components. This Grant Opportunity for Academic Liaison with Industry (GOALI) project will investigate a novel approach based on microcutting and planing-induced microfracture to enable ultra-fast, minimally invasive toughness measurement. The method has the potential to transform asset management practices across industries by allowing safer and more efficient inspection of aging infrastructure, including bridges, ships, and vintage pipelines. The research will contribute to national health, prosperity, and welfare by advancing the state of non-destructive evaluation (NDE) technologies. Additionally, the project will support the education and training of graduate and undergraduate students, helping to build a skilled workforce in manufacturing and infrastructure sectors, while inspiring broader STEM engagement through outreach activities.

The proposed method in this research project leverages a unique correlation between the cutting force and depth during microcutting, where the presence
