Journal ArticleDOI
On the shock response of cubic metals
TL;DR: In this paper, the response of four cubic metals to shock loading is reviewed in order to understand the effects of microstructure on continuum response, and experiments are described that link defect generation and storage mechanisms at the mesoscale to observations in the bulk.
Journal ArticleDOI
Spall fracture in additive manufactured Ti-6Al-4V
David R. Jones,Saryu Fensin,Olivia F. Dippo,Roberta Ann Beal,Verpnica Livescu,Daniel T. Martinez,Carl P. Trujillo,J.N. Florando,Mukul Kumar,George T. Gray +9 more
TL;DR: In this paper, a single-stage light gas-gun was used to launch a thin flyer plate into the samples, generating a region of intense tensile stress on a plane normal to the impact direction.
Journal ArticleDOI
Influence of microstructure on fatigue crack initiation in fully pearlitic steels
TL;DR: In this article, the effect of microstructure on the fatigue crack initiation of fully pearlitic steels was studied through independent variation of the prior austenite grain size, pearlite colony size, and the pearlite interlamellar spacing.
Journal ArticleDOI
Response and representation of ductile damage under varying shock loading conditions in tantalum
Curt A. Bronkhorst,George T. Gray,F. L. Addessio,Veronica Livescu,Neil Bourne,S. A. McDonald,Philip J. Withers +6 more
TL;DR: In this article, the influence of loading path on the damage evolution in high-purity tantalum is presented, and the model is shown to describe the response of the tantalum reasonably well under strongly loaded conditions but less well in the nucleation dominated regime.
Journal ArticleDOI
The influence of grain size and texture on the mechanical response of high purity hafnium
TL;DR: In this article, the effects of grain size on the mechanical response of high purity hafnium tested in compression are systematically probed and the flow stress and work hardening behavior is correlated with the substructural and textural evolution during deformation.
