摘要
在单试样三曲线关联分析的基础上,提出一种新的单试样测定断裂韧度阻力曲线的分析方法和步骤,编制了计算机应用程序。该方法反映裂纹试样的宏观断裂过程,与标准多试样法的测定结果相符。
In this work,an analytical procedure and computer program are presented to calculate the fracture resistence curve by the analysis of the relationship between the three curves of measured load-displacement,imaginary load-displacement,and ductile crack extension-displacement by using a single specimen. This method exposes macroscopic breaking process of specimen. Its analytical results agree with those of measurement by using standard multi-specimen methods.
