...× Impact damage is another form of loading that can result in specific interlaminar fracture characteristics in composite materials. In general, a delamination resulting from an impact load can often be ascertained by opening up the laminate in the plane of the delamination under mode I tension or mixed...

..., but also contribute to how a structural part will fail. Loading condition (including loading rate) plays an important role in the mode of structural failure, interacting with structural geometry and ambient environment to govern whether the failure mode is ductile or brittle. On a macroscopic scale, all...

In ductile fractures of metals with extensive gas porosity, it may be quite difficult to determine which cavities are true dimples and which are evidence of gas porosity. Mixed fracture modes: During study...
