Development of Computational and Experimental Capability forthe Simulation of High Speed Machining

这项研究的目的是发展科学基础 和计算工具， 机械加工工艺 为此，一个综合实验 并编制了计算程序， 理解和量化：（一）切割之间的摩擦 工具和工件;（ii）精确的本构模型， 工件在温度和载荷下的行为 加工过程中发生的条件，以及（iii）材料 导致产生新自由表面的失效，包括 剪切带局部化在破坏过程中的作用。

The aim of this research is to develop the scientific basis and computational tools for predictive simulations of machining processes. To this end, an integrated experimental and computational program is formulated which focusses on understanding and quantifying: (i) friction between the cutting tool and the workpiece; (ii) accurate constitutive models for the behavior of the workpiece under the temperature and loading conditions that occur during machining, and (iii) material failure leading to the creation of new free surfaces, including the role of shear band localizations in the failure process.
