INFLUENCE OF SPECIMEN THICKNESS ON FRACTURE TOUGHNESS OF MILD STEEL
Keywords:
-Abstract
The fracture toughness parameters of mild steel were investigated experimentally by using cracked
specimens with varying thickness starting from 12, 15, 20, 25 mm. The coupled effects of specimen thickness and
delamination upon fracture toughness and the mechanism of delamination are revealed; the general role of
delamination and geometry configurations on fracture toughness is found out; the initiation stress intensity factors
and fracture toughness are determined. Hence effects of variation of thickness is seen, SENB side edge notch bend
specimen is used for this experimental work. This experiment is carried out in two control either load control or
displacement control depends upon the requirement.
