... for critical rotating equipment including land-based GT with flexible operation. A probabilistic fracture mechanics (FM) methodology was developed in the 90's by Southwest Research Institute in collaboration with General Electric Aircraft Engines, Honeywell, Rolls-Royce Allison, and Pratt & Whitney...

...Mrugesh Gajjar1; Christian Amann; Kai Kadau 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 processing units (GPUs...

...Mariusz Bielawski; Kuiying Chen A computational method to evaluate fracture toughness of prospective erosion-resistant coatings using a combination of first-principles density functional theory (DFT) calculations and fracture mechanics is proposed. Elastic coefficients C 11 , C 12 , and C 44...

... by the fatigue crack growth phase and is strongly dependent on the magnitude of the stress values in the contact region. These stress values often have the most influence on small cracks where traditional long-crack fracture mechanics may not apply. A number of random variables can be used to model...

...Srikant Ranjan; Nagaraj K. Arakere A comprehensive fracture-mechanics-based life prediction methodology is presented for fcc single crystal components based on the computation of stress intensity factors (SIFs), and the modeling of the crystallographic fatigue crack growth (FCG) process under mixed...

...Michael Besel; Angelika Brueckner-Foit The lifetime distribution of a component subjected to fatigue loading is calculated using a micromechanics model for crack initiation and a fracture mechanics model for crack growth. These models are implemented in a computer code which uses the local stress...
