Mr. Sire specializes in fracture, fatigue, and fitness-for-service assessment of mechanical systems. He has more than 40 years of experience assisting clients in evaluation of pipelines, ship structures, ground transportation vehicles, aerospace structures, and implantable medical devices.

Recently, Mr. Sire has managed a number of large, multidisciplinary teams supporting clients in domestic and international arbitrations and litigations involving gas and liquid petroleum transmission pipelines, process piping, and electric power generation equipment. His capabilities include deterministic and probabilistic fracture mechanics analysis, development of fracture and fatigue analysis software, finite element analysis, and integration of test data and performance history with analytical methods.

Mr. Sire's areas of professional focus include evaluation of damaged transmission pipelines, steam turbine failures, electric generator failures, stress and fatigue analysis design support for new product development, and failure analysis of welded structures. He has assisted clients developing implantable medical devices, energy storage systems, and offshore petroleum transport systems. Mr. Sire has also served on failure review panels for commercial clients related to nuclear fuel bundles and communications satellites.

Mr. Sire is a developer of the NASCRAC Software™, a general-purpose fracture mechanics analysis program developed by Exponent for the National Aeronautics and Space Administration (NASA). Mr. Sire has developed specialized fatigue analysis software for NASA based on measured strain histories for Space Shuttle Main Engine components, and he has developed probabilistic analysis modules for steam turbine rotor life evaluation software for the Electric Power Research Institute.
