Experimental and numerical study of AA5086-H111 aluminum plates subjected to impact [PDF]
An experimental and numerical study of medium-velocity impact (within the range of 120 m/s) has been conducted on thin AA5086-H111 aluminum square plates. Targets with different thicknesses (between 2.5 and 4 mm), stratifications and aluminum alloys have

Unique Appearance of Lamellar Cleavage Patterns on Fracture Surfaces of Ti-Based Amorphous Matrix Composite [PDF]
In order to improve mechanical properties of Ti-based amorphous matrix composites basically composed of ductile beta-Ti dendrites and brittle amorphous matrix by overcoming their inherent brittle nature, their fracture mechanisms should be verified in ...

On continuum models of ductile fracture [PDF]
Several fracture criteria are reviewed with respect to ductile fracture. It is suggested that both critical crack-tip displacement, 2Vc*, and critical fracture strain,∃*, criteria may describe the fracture of a ductile second phase rod in a ductile matrix.

Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Uncoupled material model of ductile fracture with directional plasticity [PDF]
Proposed paper deals with the application of plastic response with directional distortional hardening (DDH) in uncoupled ductile fracture model and comparison of the results with the same ductile fracture model based on isotropic J2 plasticity.

FATIGUE AND TENSILE FRACTURE SURFACE MORPHOLOGIES OF ADDITIVE MANUFACTURED AUSTENITIC STAINLESS STEEL [PDF]
Fatigue and tensile fracture surface morphologies of laser additive manufactured (LAM) stainless steel (using powder bed fusion method) were investigated. Both fatigue and tensile fracture surface morphologies were determined using LEO-VP SEM instrument.

Application of a Tensile Test Method to Identify the Ductile-Brittle Transition of Caramel
During cutting of foods, tensile stresses in front of the blade are responsible for the separation of the material. Therefore, tensile tests can be helpful to gain knowledge on deformation properties related to pre-fracture cutting behavior as well as on
