Damage controlled by brittle particles crush in …

2019-5-1 · The distribution of damage controlled by brittle particles crush in AA7075-T6 beneath spherical indenter was obtained experimentally and predicted analytically. Micro hardness tests were conducted on the vertical sections across the indentation impression and by comparing it with the estimated ideal micro hardness, the damage beneath spherical indenter can be quantified.

Brittle Fracture Mechanism

In this context, brittle fracture refers specifically to fracture by cleavage or brittle intergranular mechanisms, where the fracture toughness can be characterized by a single value only. In the fracture toughness test of a brittle material, failure appears as an instability in the load displacement curve, and in LEFM the characteristic value of toughness is referred to as K IC (see Chapter 7.02 ).

Gemstone Hardness and Wearability

Diamond is the hardest natural material in the world. However, it''s also brittle. Scientifically speaking, gemstone hardness measures the ability to resist scratching, nothing more. A gem''s overall wearability grade takes its hardness into account. However, it''s only one of several factors to consider.

9.1 Failure

Consider a very brittle material, such as a ceramic or glass, or cold metal. Such a material will fracture with a "clean break". If there is no permanent deformation, the stress-strain curve in a tension test up to the point of failure will look something like that in Fig. 9.1.1.

Brittleness

Brittleness identifies material easily broken, damaged, disrupted, cracked, and/or snapped. Brittleness can result from different conditions such as from drying, plasticizer migration, etc. Brittle materials exhibit tensile S-S behaviors different from the usual S-S curves. Specimens of such materials fracture without appreciable material yielding.
