PERFORMANCE OF WELDED STRUCTURES ON COMPUTERS
OF HYBRID ARCHITECTURE
Abstract. The authors consider high-performance computational algorithms for computers of hybrid architecture to solve problems of predicting the stress-strain state of critical welded structures with regard for initiation and development of subcritical fracture of metal in accordance with the characteristic problems of analyzing the operability of welded pipeline elements with corrosive defects of metal discontinuity according to mechanism of low-cycle fatigue.
Keywords: mathematical modeling, high-performance computing, hybrid algorithms, stress-strain state, ductile fracture, welded structures.
