Failure Investigation requires a comprehensive understanding of the nature of materials, environment and operating loads to aid in identifying the root cause of a failure. There are often several contributing factors that combine to produce such a failure. In some cases, two structural components that are perfectly acceptable separately can fail when placed in close proximity to one another. For example, an interaction between the operating equipment and the supporting structure might create a destructive resonant operating condition resulting in equipment failure. Frequently, the steady and cyclic load components are not known. For these cases, failure investigation offers an excellent opportunity to define the actual magnitude and frequency of the operating loads. SimuTech Group has extensive experience integrating testing, analysis techniques (CFD and FEA), metallurgical results, potential failure modes, fracture mechanics and operating data to facilitate solving industrial failures of stationary and rotating equipment, such as blade failure analysis.
