Which one below is not true for
mechanical properties of ceramics? *
The fracture strength increases with
decreasing specimen size because as
specimen size decreases, the probably
of the existence of a flaw of that is
capable of initiating a crack diminishes.
Crystalline ceramics are harder yet
more brittle than metals because they
(ceramics) have fewer slip systems,
and, therefore, dislocation motion is
highly restricted.
Any residual porosity remained in
ceramic samples due to powder
processing techniques has a superior
influence on the mechanical properties
as they reduce the cross-sectional area
and act as stress concentrators

There may be significant scatter in the
fracture strength for some given
ceramic material because the fracture
strength depends on the probability of
the existence of a flaw that is capable c
initiating a crack; this probability varies
from specimen to specimen of the
same material.
