The Possibilities of Evaluating the Yield Strength in The Heat Affected Zones of a Weld Through Indentation HANUS Petr 1,a *, SCHMIDOVÁ Eva 1,b 1Jan Perner Transport Faculty, University of Pardubice, Pardubice, Studentská 95, Czech Republic apetr.hanus@upce.cz, beva.schmidova@upce.cz, Keywords: Mechanical properties, indentation method, microstructures, hardness, tensile test.
These zones represent critical areas of welded constructions because of a changing structure and different mechanical properties than the basic material possesses.
The indentation data were recalculated to the mechanical properties in shear with the help of Hencky´s hypotheses about material behaviour.
A very important problem comes in the case of micro-alloyed steels, which get their specific attributes thanks to the above mentioned factors [5].
DOMEX 700MC has obtained its mechanical properties by a quenching process.

Experimental investigation of mechanical properties and forming capabilities in thin magnesium sheet at elevated temperature Muhammad Waseem Soomro1,a , M.
This paper investigates the mechanical properties and forming capabilities of magnesium ZE10.
Mechanical properties are observed by stress strain diagram.
Many authors have confirmed that major factors that are affecting SPF are higher temperatures (< 0.5Tm, where Tm is melting temperatures) and fine grain sizes (where grain size is less than 10µm).
The factors that we can observe from these curves are listed in table 1.

Flat workpiece layout: 1 and 3 - heat affected zones at the “edge”; 2 - central zone with initial mechanical properties In each zone while solving the problem we have set different mechanical properties.
Thus, in the absence of a heat affected zone the mechanical properties in all three zones were assumed to be equal, with the presence of this zone – as different.
Afterwards, on a rectangular flat workpiece we marked out its “edge” – a heat-affected zone with a width of 0.5 mm, where we set mechanical properties different from those of the central zone as shown in Fig. 1 and Table 1.
Due to the lack of experimental data, mechanical properties of the material in the heat affected zone after laser cutting must be finely defined.

Mechanical Properties of Dissimilar Welds Between Stainless Steel and Mild Steel Shamsul Baharin Jamaludina, Mazlee Mohd Noor, Shahzan Kamarul A.
The mechanical properties of welded joint were investigated by tension test.
In the 1994s, Odegard et al. [3] investigated the welded duplex Alloy SAF 2507 to carbon steels in term of fusion zone mechanical properties.
It was reported that the variation in mechanical properties across the weld can be attributed to several factors such as residual stresses, grain size, phase composition and metallic inclusions [6].

Factorial ANOVA was applied to determine the significance of factors affecting creep of concrete at 3000 days using R software.
Results This study aims to investigate the significance or effective weight of factors affecting creep of concrete at 3000 days in order to determine the most factors influencing creep.
For that, factorial ANOVA was performed using R software and examined eight factors affecting creep strain at 3000 days.

So loading form and loading level are directly affecting the outcome of simulation tests
(4) Physical mechanical properties and stability of similar material: Obviously, the physical mechanical properties and stability of similar material are directly affecting various similarity principles, and then the similar extent is affected, finally, the physical simulation test results are affected.
Influencing factors on similar material mechanical properties Material that used in similar material physical simulation tests in geotechnical engineering are composite materials that compounded by aggregate and cementing materials.
It can be seen from description of above processes, primary physical mechanical properties of similar material is one of the most important factors that determine batch formula, mixture ratio of composite similar material.
Factors that affect the primary physical mechanical properties of similar materials, its primary includes: batch formula and mixture ratio of similar material (cement/sand ratio), bulk density, fillings, proportion, and water content and drying time of composite similar material and so on.

The results indicate that D/d ratio, welding speed are the most significant factors, followed by tool tilt angle in deciding the mechanical properties of friction stir welding aluminum alloy.
FSW joints have improved mechanical properties and are free from porosity or blowholes compared to conventionally welded materials.
The three factors used in this experiment are the D/d ratio, tilt angle and welding speed.
· The practical benefit of this study is that, the use of obtained optimum condition improves the mechanical properties of Aluminum alloy 6061-T6
· Tensile properties at optimum condition (i.e.

Factors affecting the Accuracy of Computations of Historic Structures MAROUŠKOVÁ Aneta1, a * 1 Faculty of Civil Engineering CTU in Prague, Thákurova 7/2077, 166 29 Praha 6 Dejvice, CZ aaneta.marouskova@fsv.cvut.cz Keywords: Historic structures, numeric analysis, FEM.
Possible approaches to the computation of historic structures and factors affecting the precision and accuracy of the results are presented in the paper.
The article presents specific examples of structures on paper and possible variations in the results obtained by considering the relevant factors.
Furthermore, masonry structures show an enormous scatter of mechanical characteristics.
The generally known mechanical behaviour of non-reinforced masonry structures is characterised by very low tensile strength.

It was concluded that the oxygen content was one of the key factors to influence the microstructure or mechanical properties of WC-FeAl composites.
Unfortunately, the WC-FeAl composite has lower mechanical properties than the WC-Co normally.
Fig. 2 shows mechanical properties of various WC-FeAl composites.
The generation of Al2O3 phases under the existence of oxygen and FeAl is a factor for degradation of those two properties.
Fe3AlC0.5 peaks are so slight for three samples that generation of Fe3AlC0.5 hardly affects the mechanical properties.

Expectedly, the mechanical properties of the nanocomposites have a degree improvement.
Values of the mechanical properties of each group were decided by the means of five samples.
Meanwhile the orientation of MWCNTs in PC matrix was changed, thus affected the mechanical properties of the composites.
The MWCNTs content was the most dominant factor which would enhance the mechanical property of MWCNTs/PC nanocomposites.
Besides, the mechanical properties and SEM analysis showed that the injection conditions were also one of major factors which would obviously affect the mechanical properties of MWCNTs/PC nanocomposites.
