Resumen
According to BS 8571:2014, standard J-R curves from SENT geometry can be determined from single or multiple specimens. The recommended methodologies for single specimen include unloading compliance or DCPD, although any validated technique can be used. The normalization method, which is not directly recommended in BSI standards, is an alternative. J-R curves through normalization technique based on P-CMOD records were experimentally determined using SENT specimens (0.40 < a0/W < 0.55) of two structural steels, later compared with the ones measured by unloading compliance. Results indicated that the normalization method is a valid alternative for J-R curve determination using SENT specimens.
