“…This may entail an enormous effort for large components with a huge number of relevant stress concentrations. Although certain simplifications allow a fatigue estimation with reduced numerical effort 6 , the correct description of the component related material behaviour is still the key requirement to be achieved prior to any fatigue life assessment.…”

The material behaviour of forged components is subjected to an intensive influence of the manufacturing process. The local logarithmic strain as well as the cooling conditions may influence the cyclic stress-strain behaviour as well as the fatigue behaviour of the material. For a reliable lightweight design of components, those effects have to be considered already during early product development stages, because the definition of the component geometry will already imply process related limitations regarding the achievable local material propeties. A combination between a process simulation and a strain-based fatigue life estimation, including a customized testing strategy, allows a consideration of the manufacturing process influence as well as an implementation of statistical and mechanical size effects and improves the quality of the fatigue assessment and the reliability of numerically derived stress limits for component design compared to the state of the art.

The study aims at the sustainable development of the Internet of Things. This paper studies the industrial product design service system and understands the relevant knowledge and theories of the industrial product design service system on the basis of literature data, and then the sustainable development of Internet of Things is set as the goal, and the industrial product design service system is designed and tested. The industrial revolution in the 18th century brought about technological innovation and economic take-off in today’s society, which completely changed people’s lifestyles and was also accompanied by a series of environmental, social, and economic problems. Abnormal weather, lack of resources, and serious waste are becoming more and more obvious. The study problem that needs to be solved urgently is the contradiction between the environment and the economy. As a result, many companies, organizations, and individuals gradually began to find effective ways and means to solve this problem, and the concept of sustainable design came into being. The study test results show that the overall system evaluation designed in this paper is relatively good: 67% of the system function evaluation scores above 3, and 66% of the system interface evaluation scores above 3 points.
