Influence of micro-crack on the propagation of a semi-infinite crack [PDF]
, 2020 The main objective of this research is to determine the influence of micro-crack on the propagation of a semi-infinite crack. This study is mainly based on the determination of the strain energy during the interaction between the semi-infinite crack and the neighboring microcrack.
