Unstable neck formation in Tensile Bars During High-Rate Tension

Nilsson, Kristina LU and Sörensen, Niels J (2000) Second International Symposium on Impact and Friction of Solids, Structures and Intelligent Machines
Abstract
The time evolution of incipient necks is studied numerically for planar and axisymmetric bars subject to high-rate extension. The material is taken to be elastic-plastic and fully non-linear dynamic effects are accounted for. Two main types of growth of necks are observed; stable neck-development that results in fully developed necks and unstable neck-development that leads to weakly developed necks, since the incipient localization stops at an early state.
