As with several methods of birth control, a wide range of failure rates has been recorded for the various types of periodic abstinence, extending from one pregnancy per 100 women-years of exposure to more than 20 per 100.
This dependence is reminiscent of biological systems, which exhibit a range of failure behaviors with limited materials and varied geometry.
The specimen details were varied to ensure a range of failure modes including both end-plate and bolt yielding.
Surgical implants are exposed to severe working conditions and therefore a wide range of failure mechanisms may occur, including fatigue, corrosion, wear, fretting and combinations of them.
These mechanisms act simultaneously and synergistically during fracture, masking their individual roles and often resulting in a wide range of failure modes in the same material.
The large volume of synthetic data thus generated over a range of failure modes along with the available test results are used to evaluate different equations for calculating the strength of such cold-formed lipped channel beams.
However, most of the chapter is dedicated to detailed descriptions of the various projectile defeat mechanisms and the wide range of failure modes that can occur in armour materials.
It is important to read all covering notes carefully because, for a given temperature and environment, a stated component may exhibit a wide range of failure rates despite the same description.
In 3D, a variable fracture plane angle is taken into account with the method, which means that the whole range of failure modes, from tensile through shear-dominated to compressive failure can be covered in a single approach.
It is shown that there is overlap in the distributions of the driving forces for surface vs. subsurface crack formation in the low to moderate range of failure probability based on FIPs; however, at higher failure probability levels, the driving forces are highest for surface crack formation.
