A novel procedure to determine the cohesive law In DCB tests

A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the crack advance is determined based on an analytical approach where the compliance...

description A novel method is presented for the determination of mode I cohesive law for the characterization of delamination in unidirectional carbon fiber reinforced polymer laminates. The energy release rate as a function of the crack advance is determined based on an analytical approach where the compliance variation of the specimen as crack advances is used in order to obtain the crack length for every pair of load and displacement data.
