Mechanical and Fracture Testing
In many types of service the mechanical performance and structural integrity
is of major importance. Mechanical testing can provide information on the
load carrying capabilities of the materials of construction. Additionally,
fracture mechanics testing and analysis can be utilized to determine the
effects of cracks in engineering materials. In corrosive service, these
effects are heighten by environmental cracking (i.e. stress corrosion
cracking, hydrogen embrittlement, liquid metal embrittlement, corrosion
fatigue). Test methods are available which combine the effects of
corrosion with fracture testing methods. These tests can provide valuable
information to determine the long term integrity of exposed components
and equipment.
