... Definitions and Basics The mechanical behavior of materials is described by their deformation and fracture characteristics under applied tensile, compressive, or multiaxial stresses. Determination of this mechanical behavior is influenced by several factors that include metallurgical/material variables...

In a smooth cylindrical tensile specimen, failure most commonly initiates by inclusion-matrix interface debonding near the centerline. This results in a central fibrous region, which is normal to the applied load...

The question is, however, whether occasional impacts or shocks can be assuredly avoided. This risk could...
