ductile fracture

Extensive research has focused in recent years on understanding and modeling ductile fracture.

If a material has much fracture toughness it will probably undergo ductile fracture.

This pipe has been used as an Infrastructure pressure pipe due to its high ductile fracture characteristics.

In ductile fracture, extensive plastic deformation (necking) takes place before fracture.

Another failure mode that may occur without any tearing is ductile fracture after plastic deformation (ductility).

Charpy impact data revealed high levels of toughness with a gentle transition between brittle and ductile fracture regimes.

A constitutive model based on a pressure-dependent yield criterion is used to predict damage evolution and ductile fracture under dynamic loading conditions.

In ductile materials (ductile fracture), the crack moves slowly and is accompanied by a large amount of plastic deformation.

Nonlinear behavior, like ductile fracture, can result in a rising R curve as the plastic zone at crack tip increases in size with extension.

Fatigue, by definition, involves ductile fracture, which is usually transgranular (through the grains), although intergranular fatigue is possible under certain special circumstances.

If a material has a large value of fracture toughness, the basic principles of fracture mechanics suggest that it will most likely undergo ductile fracture.

In other words, slow earthquakes are caused by a variety of stick-slip and creep processes intermediated between asperity-controlled brittle and ductile fracture.

The model predicts the influence of porosity on plastic flow in metals and the nucleation, growth, and coalescence of internal microvoids to cause ductile fracture.

A number of numerical models have been implemented within the finite element code LS-DYNA that predict ductile fracture during tensile, high rate loading.

A pioneer in the study of ductile fracture, McClintock was an Emeritus professor in the Department of Mechanical Engineering at Massachusetts Institute of Technology.

His professional contributions revolutionized the understanding of the fracture process in engineering practice, by introducing a physical and mechanistic perspective emphasizing the plasticity aspects of ductile fracture and fatigue crack propagation.

They are defined in contrast to the faceted fractures often seen in single crystals such as semiconductor wafers and gemstones, and the high-energy ductile fracture surfaces desirable in most structural applications.

Some types of mechanical failure mechanisms are: excessive deflection, buckling, ductile fracture, brittle fracture, impact, creep, relaxation, thermal shock, wear, corrosion, stress corrosion cracking, and various types of fatigue.
