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. 

Fracture mechanics provides a rational analysis tool for characterizing toughness of materials which can be realized as the resistance of a material towards crack growth initiation and propagation.
With fully ISO 17025 accredited laboratories in the US, UK, Middle East, South East Asia, India and Europe and extensive expertise in materials testing, Element can perform fracture mechanics testing and conduct Engineering Critical Assessments (ECAs) on a wide range of materials, applications and structures. We support a wide range of industries, from ground vehicle, aerospace, and defense suppliers to the Oil and Gas, power generation and nuclear and wind power sectors. 

Specimen geometries 

Element is well equipped to perform fracture toughness testing and analysis on a vast range of specimen geometries, including but not limited to:
• Compact Tension (CT)
• Middle Tension (MT)
• Single-Edge Notched Tension (SENT)
• Single-Edge Notched Bend (SENB) 
• Extended Compact Tension (ECT)
• Centre Cracked Tension (CCT)

• Composite Materials under modes I, II and III loading

Materials class and fracture mechanics test capabilities

Our fracture mechanics experts test both high-strength ferrous, nonferrous, polymers and composite materials using advanced computer-controlled servo-hydraulic test frames. Coupled with decades of experience, and many successful applications, our advanced equipment control, data acquisition methods and processes allow us to guide you on even the most complex test results.
There is also the possibility to create a custom fracture testing analysis and accommodate any request for non-standard fracture mechanics testing protocol for your specific application or environment.
toughness chatacterization PARAMETERS

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.
Toughness characterization Parameters

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. 

Standards we test to

• ASTM E399, E1820, E1921

• BS EN ISO 7448, ISO 15653, ISO 12135 

• BS 8571, 

• DNV-RP-F108 , DNV-S-F101
