Crack opening behavior of penetrated crack under cyclic or monotonic loading

摘要

Crack opening displacements (CODs) were examined experimentally at room temperature for both plate and pipe specimens containing a surface crack. Application of COD solutions from plate specimens, as proposed by the present authors, to pipe specimens were investigated. COD after penetration could be satisfactorily determined regardless of a type of load using the OD, solutions proposed by the authors.
