By means of the finite element method crack opening displacements were calculated for long axial surface cracks at the outer wall of a pipe. The wall thickness to inner radius ratio of the pipe was 1 to 10. Following a procedure introduced be Mattheck et al. weight functions were evaluated by means
The use of simple models to study the structural dynamics and crack stability of a cracked cantilever beam subject to impact is demonstrated. A rigid-perfectly plastic material model is used, and the J-integral and tearing modulus concepts are employed in simple forms. Concise algebraic expressions
## Abstnct-Proceeding from the experimentally vindicated basis that circumferential growth of a through-wall crack in a circular cylindrical 304 stainless steel pipe subject to bending loads, is associated with a constant crack tip opening angle, the stability of circumferential crack growth is an
In bending of a finite cracked plate, the stress intensity factor (SfF) at a cracked tip is usually negative. This means that the displacement at the vicinity of the crack tip is overlapped. However, this is not reasonable. In this paper a simple model is suggested. When the SIF is negative, some pa
