With globally located state-of-the-art fracture testing laboratories, Element delivers a wide range of fracture mechanics services to help you estimate the life of your components, reduce costly repairs and improve designs and prolong a component’s life expectancy.
Our services include characterizing fracture toughness through single point critical values (CTOD, J integral and K) as well as tearing resistance diagrams (J-R and CTOD-R curves), following the guidelines of international standards including BS 8571, ISO 12135, ASTM E1820, ASTM E1921.
Materials class and fracture mechanics test capabilities
Linear elastic fracture mechanics: critical stress intensity parameter (K1C)
When a material has a very limited capacity for plastic deformation and tearing, critical stress intensity (K1c) is the appropriate parameter to be used for toughness characterization purposes.This material response is categorized under Linear Elastic Fracture Mechanics behavior. Element are well equipped to perform this category of fracture mechanics testing and analysis following the national and international reference standards.
Elastic – plastic fracture mechanics: CTOD and J-Integral
Fracture toughness characterization of materials with some plastic deformation and tearing capacity are performed using Crack Tip Opening Displacement (CTOD) or J-integral parameters.
This material response is categorized under Elastic – Plastic Fracture Mechanics behavior. Such behavior can also be characterized via CTOD or J resistance curve. Element are well equipped to perform this category of fracture mechanics testing and analysis following the national and international reference standards.
