Nucleation and Growth of Shear Flow Localization Over a Hierarchy of Length Scales and Loading Rates

9522693吉拉特这个项目是剪切流动局部化理论/实验研究的一部分，剪切流动局部化是灾难性破坏的一种形式。一种新的扭转分裂霍普金森杆技术将被用来获得关于空间变形场演化的详细信息。希望能够在不同的加载速率、材料和长度范围内更好地了解材料损伤的机理。***

9522693 Gilat This project is part of a combined theoretical/experimental study of shear flow localization, a form of catastrophic failure. A novel implementation of he torsional split Hopkinson bar technique will be used to obtain detailed information on the evolution of the spatial deformation field. It is hoped that a better understanding of the mechanisms underlying the material damage can be obtained over a wide range of loading rates, materials and length scales. ***
