摘要

研究了各向异性AISI 1018低碳钢和C260铜锌黄铜在单轴拉伸载荷作用下的塑性变形和延性破坏行为。采用数字图像相关技术对U形缺口金属板的全场表面变形进行了测量。使用Hill模型和校准的颈缩后应变硬化曲线进行三维有限元建模，以获得裂纹萌生前的力和应变历史。采用应变-失效模型对裂纹扩展进行了数值模拟。计算结果表明，整体力-位移关系、局部应变分布和破坏过程与实验结果吻合较好。

Hybrid Experimental-Numerical Investigation on Plastic Deformation and Ductile Failure of Anisotropic Sheet Metals

The plastic deformation and ductile failure behaviors of anisotropic AISI 1018 low carbon steel and C260 Cu-Zn brass under uniaxial tensile loading were investigated. The full-filed surface deformation of U-notched sheet metal was measured by digital image correlation technique. Three-dimensional finite element modeling using the Hill model and calibrated post-necking strain hardening curve was performed to obtain the force and strain history till the crack initiation. The crack propagation was numerically simulated employing a strain-to-failure model. The results from computations as global force-displacement relation, local strain distribution, and failure process are found in good agreement with experimental observations.
