Welded penstock, produced of high-strength steel and application of fracture mechanics parameters to structural integrity assessment
Апстракт
Application of high-strength steel for welded penstock increased the probability of crack-like defects and in welded joint. Structural integrity assessment procedure is presented and applied to welded penstock produced of high-strength steel, comparing crack driving force and material crack resistance in terms of J-integral as fracture mechanics parameter. The safety and structural integrity of welded penstock are experimentally verified by testing of penstock models and precracked specimens, with special attention paid to matching effect and microstructural heterogeneity in HAZ.
