Fatigue is one of the main degradation mechanisms affecting the pressure vessel integrity of pressurized water reactors and boiling water reactors [1].
Using VAL in practice, the fatigue life is affected by load or cycle sequences.
The number of blocks has also affected the results, which is three for the first set and four for the second set of block loading.

This paper analyzes the errors of two methods to the material properties of a multilayer heavyweight building construction.

Through Laplace inverse transform of interior, cross and exterior transfer functions with unit triangle temperature, response factors and CTFs can be worked out.
Therefore, through the polynomial s-transfer functions, the response factors and CTFs of a multilayer slab are easily and accurately calculated.
When are more than 1200, i.e., the material properties become very more thermally massive, the errors of DRF solution are wide-range increasing and even reach almost 100%.

Mechanical properties such as tensile strength and hardness are considered to be the response parameters in the present study.
Olcay Ersel Canyurt [3] has developed the Genetic Algorithm welding strength estimation model (GAWSEM) to estimate the mechanical properties of the welded joint for the brass materials.
It is found that the number of variables included in the correlation equations may affect the correlation coefficients.

Mechanisms of structure transformations, as well as hardness changes in the nugget and thermo-mechanically affected zones are discussed.
However, the nature of FSW joints property enhancement, caused by specific structurization of the welding materials in the nugget and thermo-mechanically affected zones (NZ and TMAZ), is not still so clear despite an activities in many laboratories around the world.
Taking into account also two facts, that the refinement of brittle particles of excess phases by mechanical failure is quite typical for severe plastic deformation [4,7,8] and the same relation between mean grain sizes of the alloys found in the initial and processed conditions, the NZ microstructure could be specified as follows: the light rings, containing larger grains and particles of higher density, should be formed preferably by the cast alloy, and, оn the opposite, - the wrought alloy predominantly has originated more dark rings.
At that the initial alloy structural condition has noticeable impact both on width of thermomechanically affected zone, and on the grain size in a nugget zone: the more extended zone at the smaller size of grains is formed from the wrought alloy side.
For effective FSW of such materials the understanding of evolution of their structure vs welding parameters comes to the forefront, being a supervised factor to receiving required structure and mechanical properties of joints.

This paper describe various deformation models, yielding and an-isotropic properties.
The deformation mode, loading history and material behaviour are essential factors that affects the maximum admissible strain.
For anisotropic materials yielding properties are directional.
The criterion does not involve any shear stresses and cannot account for the continuous variation of the plastic properties between the material axes of symmetry [10].
