【标题】Mechanism of effects of warm prestressing (WPS) on apparent toughness of notched steel specimens Part II_ Calculations and analyses.pdf(225.68 KB)
【摘要】Based on the experimental results of Part I of present work, this paper describes results of FEMcalculationsand analyses in details which identified that the effect of tensile-warm pre-stressing (WPS) on improvementof the apparent toughness of notched specimens results from three factors i.e. the residual compressive stress,macroscopic blunting of the original notch, and prestrain-deactivating cleavage initiation. The effects of threefactors are separated and is effective for each at various ext... (04-13 17:20)
