Abstract

V notches are one of the most possible cases of initiation of CRACK due to the stress concentration. On the other hand study of stress field around notches and CRACKs is very complex. In this study DIGITAL IMAGE CORRELATION method was used to obtain displacements fields around V notches with a CRACK within PMMA specimens. First STRESS INTENSITY FACTOR was calculated using the data extracted from DIC and the relation between displacement fields and SIF from William’s equation and use of linear least square technique. Since in the defined problem CRACK length and V notch depth have the most considerable effects on SIF, effect of these parameters on the results was investigated. Finally experimental results were compared with those obtained from FE and good agreement was observed.
