抄録

Influence of fracture surface interactions on fracture toughness measured by chevron notched beam (CN) method was investigated with a fracture mechanical model. The fracture surface interaction was assumed to be elastic bridging and pull out, respectively. Load/displacement curves during chevron notched beam testing were calculated in consideration of the decrease in compliance caused by elastic bridging and the increase in dissipated energy caused by pull out. The apparent fracture toughness measured by chevron notched beam method was calculated by a maximum load in the load/displacement curve. Analytical results showed that there was a little influence of elastic bridging and pull out on the apparent fracture toughness measured by chevron notched beam method, when a CN specimen with a section of 3mm×4mm (JIS type specimen) was used.
