Crack Opening Behavior of Penetrated Crack under Cyclic or Monotonic Loading

摘要

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