摘要：
The influence of hardening exponent on the intensity of stress singularity in a plastic region around a singular point in a sandwich structure was investigated using finite element method (FEM). A piece of copper is placed as an interlayer between ceramic layers and then exerted by a four-point bending load. The material properties in the plastic region of copper were varied by hardening exponents (n = 0 to 1). The result shows that the intensity of the stress singularity in the plastic region was high as the hardening exponent approached a perfect plastic. (C) 2019 Elsevier Ltd. All rights reserved.
