構造用鋼의 疲勞크랙 發生 및 傳播에 關한 硏究

吳世旭 東亞大學校 1975 東亞論叢 Vol.12 No.2

There have been a number of investigations on the basic study for the fatigue problems, but it has not yet been clarified enough for the mechanism of fatigue failure. In spite of numerous investigations on the fatigue behavior of mild steel, it is seldom to obtain any information on the reports about the behavior of fatigue crack propagation and its mechanism of spring steel, which is widely applicable data for the structural design. This study aims to clarify the behavior and basic mechanism of fatigue crack propagation through observation and study such as the fatigue crack propagation, its propagation rate, stress intensity factor and fractograph on spring steel by using a rotary bending fatigue testing machine. And also mild steel tested its behaviors in comparison with spring steel. The results obtained in this study for spring steel are summarized as follows; 1) The initiation of fatigue crack for spring steel occurrs after 10∼20 percent of fatigue life in case of stress level such as fatigue limit. 2) The following relation is obtained from the present experiment on the fatigue crack length, normal stress and repeated cycles: ?? 3) The summarized relationship between crack propagation rate and stress intensity factor of the spring steel is as follows: ?? 4) In the crack initiation in the vicinity of the transverse hole, the slip band is generated and accumulated toward the maximum shearing stress direction and finally grown to the micro-crack. 5) The spring steel has very few micro-cracks and a great influence of nonmetallic inclusions and alloying elements on crack propagation. On the other hand, it has a tendency of more rapid propagation along or through the boundary of the matrix, pearlite grains and inclusions, as compared with the low carbon steel. These phenomena obviously come from the raised stress level above the endurance stress. 6) It is founded that several cracks is appeared in great value of the ratio between acting stress and fatigue limit, and a few crack is appeared in small value of those. This tendency assured at fracture surface both spring steel and mild steel in case of unnotched specimen. 7) Unpropagated fracture area is positioned to the center of bar section and its area becomes larger as the stress level is increased. However, at low stress level, it is located to the side of bar section with a shrunk area of fracture. The slewing appears on the fracture surface, which is induced to the anti-direction of the revolution.

The purpose of this study was to compare the retention and fitness of crown treated with various desensitizing agents on natural teeth. Varnish, dentin primer, bonding agent and potassium oxalate treated groups and control group with no treatment were used. The retention test was executed with the Instron test machine(Instron Co.,U.S.A.) on 24 hours after cementation with zinc phosphate cement. After retention test, the teeth and crowns were washed and recemented. The cemented crowns were embedded in clear resin and sectioned with a diamond saw. The occlusal and marginal fitnesses, were measured indirectly with a stereomicroscopic photographs. The result of this study were obtained as follows : 1. The retention of control group was higher than any other desensitizing agent treated group. 2. The differences of retention among varnish, dentin primer, bonding agent and potassium oxalate treated groups were not statistically significant. 3. There were no statistically significant difference in fitness at occlusal surface and margin among control, varnish, dentin primer, bonding agent and potassium oxalate treated groups. According to these results, desensitizing agents used to protect the pulp from irritation of luting agents may adversely affect the retention of castings. Therefore, desensitizing agents should be used in limited areas carefully.

精密 鑄造法의 硏究 : 精密鑄造用 國內産 珪砂에 關하여 ON THE DOMESTIC SILICA SAND FOR PRECISION CASTING

吳世旭 東亞大學校 1963 東亞論叢 Vol.1 No.-

The rapid progress of casting skill since the World War Ⅱ has been in accordance with to the requirement of the higher accuracy and higher efficiency of casting process. Namely, the demand of extra-hard-heat proof alloy requires the higher accuracy of castings, because the forging or cutting of such alloy is almost impossible. Thus, the invention and development of the precision casting, that is, Investment process, Shell Mould Process, CO₂process and Show Process have been brought about. In order to develop such a field of precision casting in our country too, I have made, through experiments, a study of the adaptability of the domestic Silica sand for precision casting. As the result of the experiments, I have found that Jinhae Silica Sand and Kosung Zircon sand have as superior a quality as the imported Silica Sand.

The purpose of this study is to develope evaluation indicators for housing plan on sloped site. First, housing plan elements were derived from the previous studies, and then, the importance of elements were evaluated by expert group. AHP(Analytic Hierarchy Process) was used to calculate the weight of housing plan elements on sloped site. Housing plan elements were derived as follow; it is composed by 6 categories and 25 detail elements. Those 6 categories are composed of 'development density', 'environmental-friendliness', 'landscape characteristic', 'building layout', 'pedestrian circulation', and 'parking plan'. The results of AHP analysis are as follows: 'building layout' is relatively important, and followed important elements are selected as 'pedestrian circulation' and 'parking plan', and then, detail elements for building layout, 'daylight', 'view', 'privacy' and 'using level' are all relatively important. Based on the degree of importance, the design and development of housing plan elements on slopes site contribute to comfortable residential-environment.

Recently the large type of steel tank has been widely used in the various industries such as the chemical, petroleum, food, water and sewerage works, pollution treatment facility industry and so on. For the safe, economical and reasonable design of those facilities, engineers have made their efforts, but even by such safety designs, there have happened unanticipated accidents, which have caused not only the damage of life and property but also the death of earth and sea by their pollution. The causes of those accidents have occurred from the problems of design, execution, low cycle fatigue, stress concentration or excessive residual stress, etc. Therefor, even after the complete design, the nondestructive measurement just before a test run after having manufactured the facilities should be necessarily carried out to prevent any accident. This study on the conical type large digester tank built, first in Korea, at the Yongho-dong Sewage Treatment Plant in Busan was dealt with the experimental consideration of its safety by using the strain gauge method, and the results are as the following: 1. The strength of the welded zone in circumferential direction at the shell plate of conical type tank is in safety. 2. By the first hydraulic test result, the maximum stress was brought about at the junction T welded zone in circumferential and axial directions near cone-skirt support bearing. By the second hydraulic test result, the safety strength was obtained more than the calculated values by the preloading effect. 3. The welded zone at the cone-skirt support bearing are under compression stress all in three axies directions, and their strength is in safety.
