Silicon Carbide Reinforced Aluminum—A Formable Composite
TLDR
In this article, a class of composites fabricated from inexpensive constituents, silicon carbide made from rice hulls and aluminum, which can be processed by conventional metal working techniques, is described.Abstract:
This paper describes a class of composites fabricated from inexpensive constituents, silicon carbide made from rice hulls and aluminum, which can be processed by conventional metal working techniques. Aluminum/silicon carbide composites can be extruded, rolled, forged, and pressed into engineering shapes. The mechanical properties of these composites as a function of silicon carbide loading fraction and aluminum matrix in a variety of shapes are presented.read more

Effect of fibre debonding in a whisker-reinforced metal
TL;DR: In this article, the debonding behaviour at the interface is represented in terms of a cohesive zone model that describes decohesion by normal separation and tangential separation, and the effect of friction during pullout is included in the model.

Theory for determining K Ic from small, non-LEFM specimens, supported by experiments on aluminum
TL;DR: In this article, a new method is presented for measuring the plane-strain fracture toughness of ductile materials, which is much simpler than JIc measurements, yet retains the advantage that the specimen can be much smaller than is required for a valid KIc test.
Failure modes in composites. II

TL;DR: In this paper, a book failure mode in composites is discussed, i.e., the book failure modes in composite composites can cause the book not to fit in the composites.

An experimental evaluation of the slotted-tension shear test for composite materials
TL;DR: The slotted-tension shear test as mentioned in this paper provides an accurate method of measuring the inplane shear response of fiber-reinforced composite materials, and it is shown that reinforced materials of any combination of fibers and fiber orientation can be tested using the new shear-testing technique.

Short Rod KIC Measurements of Al2O3
TL;DR: Fracture toughness measurements of ceramics have traditionally been made with side-grooved double cantilever beam (DCB) specimens (1-7), single edge notch bend (SENB), double torsion specimens (7,10,11), and work of fracture specimens (12-15).
