The maximum shear stresses included are observed to be much less than the Yield strength of materials.
In all the load cases, the maximum principal stresses experienced by the aircraft’s fuel tank are observed to be much less than the ultimate stress of the material.
Also in the static test pressure load case, which is considered to be the critical among all the other cases, the maximum shear stresses included are observed to be much less than the Yield strength of materials (345Mpa).

Because the released heat of the material in the period of char oxidation reaction can not warm-up the unburned materials and can not meet the oxygen demand in the material, the smoldering is not able to spread.

For the same photon energy, this device has a lower value of α compared to Ge (α = 1.45 × 104 cm-1) and InGaAs (α = 2.18 × 104 cm-1).[19], [20] Overall, the α value above the energy bandgap is around 104 cm-1 which is within the estimated range for III-V semiconductor materials.
Other work on Bi-based material systems have reported similar behaviour due to disorder of the material and the tail can be extended about <100 meV below the bandgap.[13], [22]–[24].
