Energy Release Rate Tests

Energy Release Rate (ERR) Tests measure how much energy is needed for a crack to grow in a material. During the test, a crack is introduced or made to grow, and the amount of energy required to extend it is calculated. This helps engineers understand the material's resistance to fracture and its ability to withstand stresses without cracking further. ERR testing is essential in predicting failure and ensuring safety in structures like aircraft, bridges, and electronics by evaluating their durability under real-world conditions.
