Abstract This paper is devoted to research the interface failure mechanism of coating in gun barrel, three models (interface shear failure, bending and crack growth failure) barrel are built with consideration thermal-pressure coupling effect, criterion given. The critical length/thickness ratio segments for different during firing process calculated based on temperature field simulation result...

Effectiveness of testing criteria is the ability to detect failure in a software program. We consider not only effectiveness of some testing criterion in itself but a variance of effectiveness of different test sets satisfied the same testing criterion. We name this property "tolerance" of a testing criterion and show that, for practical using a criterion, a high tolerance is as well important ...

The competing risks model is useful in settings in which individuals (or units) may die (or fail) due to a number of different causes. It can also be the case that for some of the items the failure cause is known only up to a subgroup of all causes in which case we say that the failure is group masked. A widely used approach for competing risks data with and without masking involves the specifi...

The impact of CMOS technology scaling on the second breakdown of ESD protection devices has been investigated using 2-D simulations and analytical calculations. It is shown that the second breakdown trigger current (It2) can not be reliably used as an ESD robustness criterion in sub-0.18 um ESD protection devices. When a technology feature size is reduced, the doping of drain and drain extensio...
