✦ Synopsis

A theoretical estimate is made of the effect of pin friction on values of the stress intensity factor forthe ASTM type single edge notch fracture toughness test specimen. It is shown that for a coefficient of friction of 0.2 between pins and specimen the stress intensity factor is reduced by approximately 10 per cent. It is therefore concluded that precautions must be taken to keep friction to a minimum when measuring fracture toughness using this type of specimen.
