Abstract

The paper derives from a simple question that the authors have asked themselves when attending conferences and reading articles on modelling of metal forming processes: is numerical modelling based on FEA still innovative? Are the proposed results able to provide a further effective enhancement to scientific knowledge? And how huge was the effort to obtain such an eventual enhancement? Starting with these questions, the authors applied some basic concepts of Innovation Theory to the last forty years of numerical modelling of forming processes and understood that this technology has reached its natural limit: only small enhancements of modelling performances are obtained despite quite big efforts. Also, research topic trends analysis was performed within ESAFORM community through text mining approaches. Now, to answer the research questions still open, a disruptive discontinuity is necessary, aimed at assessing a new master modelling technology.

创新理论在金属成形建模中的应用：FEM的黄昏与AI的黎明？

本文源于作者在参加会议和阅读有关金属成形过程建模的文章时问自己的一个简单问题：基于有限元分析的数值建模仍然具有创新性吗？建议的结果是否能够进一步有效地提高科学知识？为了获得这种最终的增强，付出了多大的努力？从这些问题出发，作者将创新理论的一些基本概念应用到近四十年来成形过程的数值模拟中，并认识到这项技术已经达到了它的自然极限：尽管付出了很大的努力，但建模性能只得到了很小的提高。同时，通过文本挖掘方法对ESAFORM社区内的研究课题趋势进行分析。现在，为了回答仍然开放的研究问题，一个破坏性的不连续性是必要的，旨在评估一个新的主建模技术。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
