项目摘要
The main objective of the project prolongation is the modeling of metal forming processes coupled with the prediction of strain-induced damage. The implementation of the project comprises the solution of the following research problems: experimental study and modeling of damage in multistage forming processes accompanied with intermittent healing operations via heat treatment; modeling of non-steady-state forming processes coupled with a prediction of strain-induced damage for variable values of stress triaxiality and Lode angle with the use of systematized experimental data both from own and external works. A thermodynamically consistent tensorial framework for strain-induced damage developed in frames of the project, the performed experiments and numerical modeling as well as the results recently published both by the applicant and by other authors will provide a sound scientific basis for achievement of the project objectives. A solution of the scheduled research problems will enhance the theoretical and methodological background of ductile damage mechanics and will extend its application-oriented possibilities to relevant engineering and processing issues in metal forming industry. The project results will be applied to the development of advanced forming processes.
项目延期的主要目标是金属成形过程的建模以及应变损伤的预测。该项目的实施包括以下研究问题的解决方案:在多阶段成形过程中伴随着通过热处理的间歇性愈合操作的损伤的实验研究和建模;非稳态成形过程的建模,再加上预测的应变引起的损伤的变量值的应力三轴度和矿脉角与系统化的实验数据都从自己和外部的工作。在该项目的框架中开发的应变诱导损伤的热力学一致张量框架、所进行的实验和数值建模以及申请人和其他作者最近发表的结果将为实现该目标提供良好的科学基础。项目目标。预定的研究问题的解决方案将提高韧性损伤力学的理论和方法背景,并将其应用为导向的可能性,在金属成形工业的相关工程和加工问题。项目成果将应用于先进成形工艺的开发。
