Numerical determination of plastic
AbstractIn previous works, a da/dN versus plastic crack tip opening displacement model was proposed to study fatigue crack growth. The plastic crack tip opening displacement, δp, which quantifies the crack tip plastic deformation, is determined numerically using the finite element method.

Dugdale plastic zone size and CTOD equations for the compact specimen
International Journal of Fracture, 1984With the aim of applying the Dugdale model to the compact specimen, the equations for stress intensity factor and crack surface displacement are obtained for a pair of pin loads and a uniform stress acting on a segment of the crack surface. The plastic zone size is calculated from the 'finiteness' condition of Dugdale, and the results agree well with ...

Fatigue crack growth versus plastic CTOD in the 304L stainless steel
Engineering Fracture Mechanics, 2019Abstract The plastic CTOD range, δp, which quantifies crack tip plastic deformation, is used to study fatigue crack propagation instead of the classical ΔK elastic parameter. A da/dN-δp model was defined for the 304L stainless steel. da/dN was obtained experimentally in standard CT specimens while δp was predicted numerically using the finite element

J and CTOD Estimation Procedure for Circumferentially Cracked Pipes Based on Fully-Plastic Solutions
2010 8th International Pipeline Conference, Volume 2, 2010This work provides an estimation procedure to determine the J-integral and CTOD for pipes with circumferential surface cracks subjected to bending load for a wide range of crack geometries and material (hardening) based upon fully-plastic solutions. A summary of the methodology upon which J and CTOD are derived sets the necessary framework to determine
