fatigue and fracture CC Technologies has laboratory facilities for fatigue and fracture testing utilizing standard ASTM methods or specially designed procedures, as well as apparatus for specific applications not covered by standard methodologies.

Examples of these tests include:
Corrosion Fatigue
Fatigue Crack Propagation
High-Temperature Fatigue and Fracture
High-Cycle Fatigue
Low-Cycle and Thermal Fatigue
KIC and JIC Fracture Toughness
Creep Crack Growth

CC Technologies also has experience and expertise analyzing fatigue failures of materials and components and in predicting the fatigue performance of structures and mechanical equipment.

Some examples include:
Fatigue Failure of Generator Rotors
Fatigue Failure of Large Electric Motors
Fatigue Assessment of Connecting Rods
Remaining Fatigue Usage of Pressure Vessels
Fatigue Criteria for Pressure Vessels and Piping
Thermal-Mechanical, Low-Cycle Fatigue Resistance
Threshold Corrosion-Fatigue Crack Growth Rate
Fracture Criteria for Steam Pipes
Fracture of Oil Storage Tanks
Fracture of Induced Draft Fans
Fatigue of Paper Machine Components
Fatigue Life of Pulp Washer Drums
Fatigue of Aging Aircraft Components
Fatigue Strength Reduction Factors for Welded Joints

In addition to the more standard fatigue and fracture analyses, CC Technologies' scientists perform large scale research projects involving fatigue, corrosion fatigue and cyclic loading. These have included the combined interaction of cathodic protection and fatigue of marine structures, the effect of cyclic loading and hydrotesting sequence on the stress corrosion cracking of large diameter gas transmission pipelines, and the effect of existing corrosion on the propagation of fatigue cracks in aluminum aircraft components.
