Exova has extensive experience in fracture toughness testing of a variety of materials for industrial applications such as steels for fabrication of pressure vessels, offshore oil platforms and oil and gas transmission pipelines. In the aerospace market our laboratories have in depth knowledge of the fracture behaviour of high alloy steels and non-ferrous alloys such as aluminum and titanium, routinely performing many of the standard ASTM fracture tests. Utilizing the latest in engineering software our engineers can readily provide data on crack growth resistance, defect tolerance and overall fitness for purpose of alloys used in even the most critical of applications.

Typical Fracture Toughness testing carried out in our laboratories is shown below:

 

• ASTM E399 K1c Plane Strain Fracture Toughness of Metallic Materials
• ASTM E813 JIc Testing
• ASTM E1820 Measurement of Fracture Toughness
• ASTM E561 R-curve Determination
• ASTM E1290 Crack Tip Opening Displacement (CTOD) Fracture Toughness
• ASTM E208 Drop Weight Test to Determine Nil Ductility Transition
• ASTM E604 Dynamic Tear Testing
• Fracture Toughness testing can be carried out over a wide range of temperatures.
