摘要
应用FRANC2D/L对铝合金2024—T351板材I型裂纹稳定扩展进行了数值计算,阐述了FRANC2D/L的分析方法及四分之一点奇异单元的特性;分析了临界COD判据在计算过程中的应用。通过实验与计算结果的对比分析,表明了FRANC2D/L为一可行、可靠的二维裂纹稳定扩展分析工具。
Numerical calculation on stable crack tearing （ mode Ⅰ） is completed in aluminum alloy 2024-T351 by using FRANC2D/L. The simulation method of FRANC2D/L and the characteristics of 1/4 point singular element are expounded. The applications of critical COD criterion in process of simulation are analyzed. Results of the numerical calculation and experiments show that FRANC2D/L is viable and reliable in analysis of 2D stable crack extension.
