| Abstract: | 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. |
