- ABSTRACT:
The lack of a limb and function may adversely affect human life. This removal of acids in the
treatment of medical intervention, repair or remedy possible. However, the human body and system
in the human body anatomical differences in the standard prosthesis produced differences in the
structure of harmony and repetition of the problems that may arise on the settlement of the
transaction, can lead to movement in human life and health. In addition, this prosthesis, but the
adjustment process after the placement process can be monitored. In this process, the most common
problems can emerge as a good physician and operations despite sinking prosthesis prosthesis over
the slightest slip uncomfortable situations based on location. Physician experience is very important
for the placement of the prosthesis. However, if a physician's experience in achieving a higher
number of subjects studied it is inevitable. Total joint replacement, adding that changing the
damaged joint surfaces of artificial materials with function again gain stability and aims to eliminate
the existing pain. Thanks to the support of the design and modelling success during assembling
prostheses to be made available to increase the percentage increase in our study, the cost of these
works to eliminate the risk of failure and contributes to better quality of human life. Experience and
intuitive approach of physicians able to offer insight into the process as well bite the positive
approach in science as we define additional targets.
In this study, 3 steps have been applied to place a special prosthesis. Firstly, the choice of
material for the appropriate prosthesis. In the second step, the size and position of the prosthesis that
will be specially needed will be scanned and produced. Finally, placement of the prosthesis in the
body was carried out. As the first step in this article, the selection of the right material in denture
production has been examined.

COMPRESS USAGE FOR DESIGN OF A STORAGE TANK AND COST ANALYSIS OF SPOT AND FULL RADIOGRAPHIC CONTROL
- AUTHOR(S):

- ABSTRACT:
Storages or transmission tanks as a pressure vessel are important engineering equipments and
appear in various areas. The main goal of this study is to propose a simple method to solve, with
minimum effort and acceptable reasonable accuracy, the problem of designing a storage vessel
subjected to uniform internal pressure by using a commercial program. For this purpose the
COMPRESS program, which is preferred for obtaining quick results in the design of this type of
tank, has been introduced in detailed, and the design makes use of this program and also meets the
ASME Boiler & Pressure Vessel Code, Section VIII, Rules for Construction of Pressure Vessels
Division 1 standards. Then the use of stainless steel and carbon steel which is preferred in general in
the construction of tanks for full and spot radiographic control was performed. For this purpose a
storage tank has been designed for 10atm of internal pressure and a temperature of 120oC and
capacity of 1500 lt.

S. O. ERUSLU, I. S. DALMIS
- ABSTRACT:
In this study hydroforming analysis of low carbon cold formed structural steel sheets (St12, SAE
1006) are studied experimentally and numerically. The effects of hydrostatic pressure, plate
thickness, mould curvatures were investigated. The failure zones, stress and deformations were
compared with finite element model. It was found that the metal elongation and strength, plate
thickness, mould design were effective tools for hydforming performance of sheet metals. The
Bilinear isotropic hardening nonlinear material modelling with shell elements are used in Ansys 16.0
Lsdyna explicit module. The effects of element size on stress results and thinning of sheet metals at
plastically deformed place are also discussed in model. The results are found in good agreement with
the results of experimental works.

PERFORMANCES OF ABRASIVE WATER JET CUTTING WITH HYPER PRESSURE OF 900 MPA
- AUTHOR(S):
M. Radovanović
- ABSTRACT:
Abrasive water jet cutting machines operating at hyper pressure were introduced based on the
notion that increased pressure means faster cutting. Applying hyper pressure results to faster cutting,
lower abrasive consumption, higher productivity and smaller operating cost. Ultra-high pressure of
350 to 400 MPa is currently standard. However, a clear increase in performances and productivity
and decrease in cost of abrasive water jet cutting can be achieved with hyper pressure.
Performances of abrasive water jet cutting when applying hyper pressures of 900 MPa is analyzed in
this paper.

MULTI OBJECTIVE OPTIMIZATION OF PROCESS PARAMETERS FOR SINGLE PASS CNC TURNING
- AUTHOR(S):
M. Radovanović
- ABSTRACT:
Manufacture low cost and high quality machine parts and products in a short time is the most
important goal of the production in metalworking industry. In machining, multi objective
optimization is a real problem. For solving this problem modern optimization methods are used. In
this paper is presented a multi objective optimization of single-pass turning of carbon steel AISI 1045
with coated carbide tool using multi objective genetic algorithm (MOGA).
