Abstract

Corrosion is metal loss due to interaction with the surrounding environment. The consequences of corrosion are so damaging that they can have an impact on human casualties. A report from NACE in 2002 has shown that corrosion losses in the United States was about 3.1% of Gross Domestic Product (GDP). This figure was expected to increase in 2016 to over 6.2% of GDP. Overall, the losses caused by corrosion have reached 3-4% of the GDP of the industrialized countries. The numbers are very large and therefore, corrosion control are very important to be implemented. In efforts to control corrosion, research in the area has been widely conducted. Experimental research has played a very important role. However, the development of simulations in the world of corrosion is also very promising. Corrosion simulations are developed based on numerical methods. The commonly used numerical method is the boundary element method (BEM). In subsequent developments, the optimization method has also been used in the case of inverse analysis such as corrosion detection. This paper presents briefly the development of corrosion simulation which has been performed by many researchers in efforts to solve various corrosion cases.

Abstract

The objective of this research is to analyze the results of the topology optimization model Hip Stem Prosthesis in heel strike and flat foot conditions. The simulation is done using software based on finite element method ANSYS Release 18.0. Analysis of heel strike and flat foot conditions was carried out on the design of the artificial pelvic bone AML (Anatomical Modullary Locking) model. The ball head diameter used in this research was 38 mm and stem length was 140 mm. The analysis is done by optimizing the hip stem prosthesis step by step according to the condition when walking. Loading is given to the hip stem prosthesis during heel strike and flat foot with a time history of 0,01 seconds and 0,2 seconds starting from the initial position of heel strike and ending with the flat foot position. The simulation results show that the stress distribution is evenly distributed and the size of the volume of the design region varies.

Abstract

The  objective of this study is to study the influence of  anode-cathode displacement to corrosion potential distribution of reinforced concrete cathodic protection system. Reinforced concrete speciments with a length of 1000 mm, width of 100 mm, and a height of 100 mm were used. Three variations of anode-cathode displacement for the specimens were 5 mm, 10 mm, and 20 mm. Specimens were immersed in a solution of NaCl 3.5 % and treated by wet-dry cycle. Profometer 5 + was used to find the location of reinforcement without damaging the surface of the concrete. Half-cell potential digital meters was used to measure the corrosion potential value of steel reinforcement. The corrosion potential measurements after 12 weeks of wet-dry cycle shows that the most negative corrosion potential was obtained for 10 mm anode-cathode displacement, i.e-391 mV. While for 5 mm and 20 mm anode-cathode displacements were -374 mV and -378 mV. Therefore, the anode-cathode displacements might affect the distribution of corrosion potential on reinforced concrete cathodic protection system.

Abstract

This research simulates the galvanic effect on medium carbon steel from the result of heat treatment using the Boundary Element Method (BEM) -3D. BEM was developed with the assumption that the electrolyte surrounding the anode-cathode system no ions in or out, so that it can be modeled as Laplace domain. The potential value and the current density across the surface of the domain can be determined by solving the Laplace equation using the BEM. The Galvanic effects can be analyzed by using the potential data. To simulate the galvanic effect on medium carbon steel the result of heat treatment, two anode-cathode combination was set. The first combination is the annealing steel as the anode and the normalizing steel as the cathode. While the second combination is a hardening steel as the anode and the normalizing steel as the cathode. The conductivity value of the electrolyte for the galvanic effect simulation is 0.0541 Ω / m. The simulation results of the first combination showed the most negative anode potential value is -104.09 mV and the cathode potential value of -85.41 mV. While the simulation results from the second combination provides the most negative anode potential value are -220.27 mV and the cathode potential value are -85.41 mV. From the simulation can be seen that the potential difference between the first anode-cathode combinations are +18.69 mV and the second combination are +134.86. Thus, the simulation results show that the combination of annealing steel and normalizing steel produce galvanic effect is relatively small. While the combination of hardening steel and normalizing steel provide galvanic effect is relatively large.

Abstract

One of the components, namely the shaft that is subjected to torsion will experience torsional deformation. The greater the torsional deformation indicates the ability of the engine components is low, and vice versa. The problem that often occurs during torsional testing is that processing the data into a shear stress-strain curve requires a lot of effort. If the specimen used is a solid rod, there will be a fairly steep stress gradient along the cross-section of the specimen making measurements difficult. The objective of this research is to identify and analyze the torsional strength test on low carbon steel by a numerical method using SolidWorks software. The torsion test specimen is low carbon steel with ASTM E-143 standard. This research method begins with a literature study, testing the composition of the test specimen, making and modeling torsion test specimens. After that, torsional testing was carried out which was then carried out with static simulation tests. Then perform a torsional strength analysis using the finite element method using software (SolidWorks). Based on the results of geometry making and modeling of torsion test specimens with ASTM E-143 standard, that the stress distribution that occurs on the surface of the specimen angle area has a value that is not too significant, ranging from 2.879e+09 and 2.973e+09. However, it is necessary to simulate the torsion test of the SolidWorks software with varying mesh sizes and torsion test specimens with different ASTM standards.
