failure mechanism of specimens. From fractography analysis point of view different type of voids and defects were found along specimens’ surface , generating stress concentrators that contributed for crack initiation. Further studies focusing on the reduction of surface roughness and improvement of surface quality, for instance by using acetone vapor smoothing or ironing (Sardinha et al., 2020), are recommended.
