Engineering and Technology Journal, 2011, Volume 29, Issue 6, Pages 1094-1106

The aim of this paper is to demonstrate the influence of butt welding shapes
on the corrosion rate, microstructure and temperature of carbon steel type
St37.The double butt welding was performed by V angles 15°,30° and 45°. The
finite element analysis via ANSYS software is performed, this analysis includes a
finite element model for the thermal welding simulation. The temperature
distribution was obtained. From the results of the microscopic structure it is
evident that the geometric shape has an important role in the welding process,
when the geometric value of the welding region gets bigger, the faults get less due
to increase of heat quantity in the welding region and the corrosion rate for the
rain water is less than of sea water. The work presents the finite element model for
numerical simulation of welding in carbon steel St37 double butt welding.

The aim of this paper is to demonstrate the influence of butt welding shapes on the microstructure, temperature and equivalent stresses of carbon steel type St- 37.The single butt welding was performed by V angles 15°,30°,45° and U shape. The finite element analysis via ANSYS software is performed , this analysis includes a finite element model for the thermal and mechanical welding simulation. The equivalent stresses and temperature distribution were obtained. From the results of the microscopic structure it is evident that the geometric shape
has an important role in the welding process, when the geometric value of the welding region gets bigger, the faults get less due to increase of heat quantity in the welding region. The work presents the finite element model for numerical simulation of welding stresses in carbon steel St-37 butt welding. The welding simulation was considered as a direct coupled thermo- mechanical analysi.s

Effect of Shaft Misalignment on The Stresses Distribution of Spur Gears

Shaft misalignment is considered as one of the common repeated
problems in most rotating machineries , which leads to generate vibrations and
extra dynamic loads on transmitting gears teeth, also leads to non- uniformity in
distribution of applied load along the meshing tooth face by being concentrated on
one side of tooth face. The present work concentrated on the analysis of stresses
generated on transmitting gear tooth, also studied the effect of misalignment angle
on stress distribution and its concentration. This is important for the gear design
and those who works in gear maintenance , because fracture is expected to initiate
and propagate at locations of stress concentration . ANSYS program using finite
element technique had been used, as this program is efficient and accurate tool in
stress analysis, especially for complicated shapes. Gear tooth model had been
analyzed using finite element method in three dimensions. After calculating
transmitted load and dynamic load, misalignment angle had been changed from
(0°,0.2°,0.3°,0.4°,0.5°) then its effect on distribution of applied load had been
calculated. The finite element program (ANSYS) had been executed for cases of
misalignment angle (0°,0.2°,0.3°,0.4°,0.5°). The results showed clearly, that the
stresses distribution and its concentration on tooth changed with misalignment
angle and the equivalent stress is direct proportional with the misalignment angle.
According to the values of generated stresses, the tooth fracture can be predicted
