Special Issue Information
Dear Colleagues,
Because of continuous efforts to reduce the costs of metal materials production, increasing energy efficiency has become a priority task in this industry. In successful metal production plants, careful energy managing for more and more sustainable metal materials making friendly to the environment is intensively promoted. According to European standards, governments are obliged to increase energy efficiency and minimize CO2 emissions and environmental printouts. It was estimated that in the next 10 years it would be necessary to invest several billion Euros for at least a 20% reduction of CO2 emissions. The only way to realize those targets is to modernize metal production processes, equipment, and infrastructure. The most innovative approach to the modernization of plants is the introduction of cloud technologies into metal production processes. According to paradigm 4.0, digital technologies combined with artificial intelligence have the potential to transform metal production processes to a new more efficient level. Another approach to realizing these targets is to introduce advanced process optimizations regarding productivity, product quality, and cost reductions. To reduce the expensive experimental trials used to evaluate the impact of different optimization strategies, advanced process modeling is needed. Modeling and simulations serve us as an invaluable source of information for conducting process analysis and as an alternative to expensive, dangerous, and time-consuming experimental trials.
This Special Issue of Metals will cover recent advances in the modeling and optimization of different sub-processes in metal materials production from casting, rolling, heat treating, product delivery, quality assurance, and machinability assurance, while considering the most recent experimentally obtained process data.

Abstract: In this study, the computational model for fatigue analysis of structural components made of S960Q martensitic steel is presented. The flat tensile specimens with a central circular hole were thermally cut by plasma and laser technology. The total fatigue life of the studied specimens, N, is divided into the time of crack initiation (Ni) and crack propagation (Np). The number of stress cycles for crack initiation in a critical cross-section (Ni) is determined using the strain-life approach and considering the low cycle fatigue parameters previously used for the same material as in this study. The number of stress cycles for crack propagation from initial to critical crack length, Np, is determined using the simple Paris law and considering fatigue crack growth material parameters obtained from previous work by the authors. The comprehensive computational analyses in Ansys software are carried out to obtain the strain-stress field and determine the stress intensity factor in the crack tip. The computational results obtained are reasonably related to the available experimental results.
