Q. What is your terms of packing?

A: Generally, we pack our goods in neutral white boxes and brown cartons. If you have legally registered patent, we can pack the goods in your branded boxes after getting your authorization letters.

Q. What is your terms of delivery?

A: EXW, FOB, CFR, CIF, DDU.

Q. What is your sample policy?

A: We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.

In the FEM model, it is necessary to provide nonlinear behavior for the finite elements. Due to the level of stress expected on different parts of the structure, linear material properties are used for the engine and both linear and nonlinear for the EMS. Some of the energy absorbed by the model would be spent on plasticizing the material of the EMS. The nonlinearity has been included through a perfectly plastic criterion in the material for the corresponding 1D and 2D elements of the EMS model. The EMS-wing fitting has been reproduced through elements and its stiffness is changeable. Finally, the wing is replaced nominally by a clamped constraint, since the main interest is determining the forces transmitted to the wing because of blade loss.
