Crack-tip opening displacement (CTOD) measurements were made 100 üm behind the crack tip on standard three-point bend specimens using a laser-based interferometric technique. Four materials (SAE-01 steel, 4340 steel, HY-100 steel, and tungsten) were tested at loading rates ranging from quasi-static (K ≈ 1 MPa∙ m½/s) to dynamic (K ≈ 106 MPa ∙ m½/s).

Butt-welded wide plates with semi-elliptical surface cracks along the fusion line were tested in four-point bending. The material was normalized low-carbon microalloyed steel that conformed to offshore specifications. The testing temperature was in the range of -40° to 0°C.

Prediction of failure of fracture toughness specimen is possible to estimate by using crack driving force and d5(CTOD)-R resistance curve of material. Accuracy of numerically determinated points on the curve of crack driving force depends on numerical model and description of mechanical properties of material.

In the multi-passed weld heat-affected zone (HAZ), the occurrence of mechanical and metallurgical heterogeneity is inevitable. For the fracture toughness evaluation of the steel weld HAZ, the effect of the inhomogeneity shall be considered, particularly in relation to determination of the appropriate testing procedures such as the extraction of test ...

The article deals with analytical determination of stresses and displacements and some other fracture mechanics parameters, such as: the crack tip opening displacement (CTOD) and the magnitude of the plastic zone around a crack tip, in thin infinite cracked plates.
