But the principal failure is by police and prosecutors, who have primary responsibility for investigating homicides and bringing the true criminals to justice.
Delamination is not a principal failure mode.
Debonding between the FRP composite and the substrate has been recognised as the principal failure mechanism of the reinforcement system.
The principal failure mode of all bone-implant-constructs tested was the collapse of the opposite cortex, which generally occurred quickly after the initial opposite cortex crack.
Local buckling is the main failure mode for slender sections whereas the lateral torsional buckling is one of the principal failure modes for beams, thus the interaction between these two failure modes greatly affects the load-bearing capacity of the beams.
According to Richard Clarke, former national security advisor on terrorism and author of Your Government Failed You: Breaking the Cycle of National Security Disasters (2008), the principal failure of U.S. decision makers was to direct their efforts not at al Qaeda but at its state sponsor, protector, or enabler.
According to Mike Scheuer, chief of the CIA's former bin Laden task force and author of Imperial Hubris: Why the West is Losing the War on Terrorism (2004), the principal failure of U.S. decisionmakers is viewing the source of the conflict in terms of fundamentalist religious beliefs rather than as a reaction to U.S. policies toward the region.

Yet several political economy factors can severely constrain the implementation of these carbon pricing policies, including opposition of industrial sectors with a concentration of assets that would lose considerable value under such policies; the collective action nature of climate mitigation efforts; principal agent failures; and a low willingness-to-pay for climate mitigation by citizens.
The Tsai Wu and the maximum principal stress failure criteria are used to predict failure in the composite and adhesive layers, respectively, and the results are compared with the target reliability level implicitly used in the wind turbine standard IEC 61400-1.
