RISOn the Extent of Dominance of Asymptotic Elastodynamic Crack-Tip Fields: Part I—An Experimental Study Using Bifocal Caustics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The question of the domain of dominance of mode I asymptotic elastodynamic crack-tip fields is investigated experimentally for the cases of dynamically loaded stationary cracks as well as ...

Three-Dimensional Effects Near a Crack Tip in a Ductile Three-Point Bend Specimen: Part II—An Experimental Investigation Using Interferometry and Caustics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation is undertaken to assess three-dimensional effects near a crack front in a ductile three-point bend specimen. The possibility of using the optical method of caustics ...
On the Extent of Dominance of Asymptotic Elastodynamic Crack-Tip Fields: Part II—Numerical Investigation of Three-Dimensional and Transient Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part I of this paper, the question of the extent of dominance of the mode I asymptotic elastodynamic crack-tip field (the K d I -field) was studied experimentally. Here, the results of ...
