RISProbabilistic Fracture Mechanics for Heavy-Duty Gas Turbine Rotor Forgings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We developed and successfully applied a direct simulation Monte Carlo (MC) scheme to quantify the risk of fracture for heavy-duty rotors commonly used in the energy sector. The developed probabilistic fracture mechanics ...
Probabilistic Fracture Mechanics for Mature Service Frame Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large gas turbine design and service business are challenged with increased demands toward flexible operations, increasing number of start-stop cycles, and intermediate cycles. Probabilistic fracture mechanics simulation ...
A Probabilistic Model for Forging Flaw Crack Nucleation Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A probabilistic model for quantifying the number of load cycles for nucleation of forging flaws into a crack has been developed. The model correlates low cycle fatigue (LCF) data, ultrasonic testing (UT) indication data, ...
High-Performance Computing Probabilistic Fracture Mechanics Implementation for Gas Turbine Rotor Disks on Distributed Architectures Including Graphics Processing Units
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present an efficient Monte Carlo-based probabilistic fracture mechanics simulation implementation for heterogeneous high-performance computing (HPC) architectures including central processing units (CPUs) and graphics ...
A Probabilistic Model for Forging Flaw Crack Nucleation Processes for Heavy Duty Gas Turbine Rotor Operations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a probabilistic model for quantifying the number of load cycles for nucleation of forging flaws—for a 3.5NiCrMoV high strength low alloy rotor steel—into a crack under gas turbine operating conditions. The model ...
