The time ([t.sub.p]) at which the brittle failure
occurred is then substituted into Eq.
For samples with cracks and good integrity, samples showed brittle failure
. For samples with many corrosion pores showed ductile damage under natural and saturated state, and the spalling phenomenon was enhanced under the saturated state.

To simulate the failure and crack propagation process of shale during Brazilian splitting testing and verify the accuracy of the established brittleness evaluation model, the discrete element method is utilized to establish the Brazilian splitting test model for layered shale and conduct a numerical simulation on the tensile brittle failure
It is a very straightforward check to perform during the design stage, but if not considered, this can result in an erroneous design which can eventually lead to an undesirable brittle failure
. The response of a beam with a departure from this provision is presented to highlight the significance of the problem.
The plastic deformation and brittle failure
behavior of Yamaguchi Marble under triaxial compression is simulated by the DEPM model via ABAQUS explicit scheme.

Fracture parameters used in experiments are given brittle failure
conditions with initial velocity.
Residual stress will often lead to brittle failure
, so the part must be carefully designed, molded, sometimes post-treated, and attention must be paid to maintaining tolerances.
All these fracture FNCT samples surface shows more brittle failure
in terms of FNCT terminology according to the ISO 16770 .
The increase in the reliability levels for brittle failure
modes is achieved by setting a lower resistance factor than that associated with ductile failure modes.
