Virtual experimenting – considering actual material behavior and imperfections – is invoked for the calibration of the model.
However, welding vertical stiffeners causes softening of the material of the whole cross-section, resulting in several weak points in the member along its length.

It is shown by available theories and experiments that quasicrystals are new, promising materials with a complex structure and unusual properties[1-2].
From Ref. [2], when dislocations parallel to the quasi-periodic axis of 1D hexagonal quasicrystals, the geometry properties of the materials will not change with quasi-periodic direction.
The materials with the elastic properties 11 1 44 3 44, ,C R K and 22 2 44 3 44, ,C R K occupy the inhomogeneity S+ and the matrix S− , respectively.
The two materials are assumed to be perfectly bonded along the interface.

Pb(NO3)2, NaOH, and SC(NH2)2 were used as raw materials to prepare PbS films via Chemical bath deposition method.
Comparing to the PDF card, this material should be Pb2SO5, which is important to improve photosensitive property of the film [11].
Linear fitting for lnRT~1/T has been made by least square method in the low temperature region, and then the formula ΔE = kB has been used to find the average impurity activation energy, where k is Boltzmann constant, B is the slope of lnRT~1/T after fitting as a straight line, and ΔE is the impurity activation energy in thermo-sensitive materials.

The full development of SiC-devices is however still limited by the high defectivity of bulk material, which could be only partially overcome by using epitaxial procedures [1].
This technique has been applied also to SiC and resulted very helpful in detecting various impurities and defects present in the material.
