In order to predict failure behavior of advanced high-strength steel sheets (AHSS) in hole expansion tests, damage model was developed considering surface condition sensitivity (with specimens prepared by milling and punching: 340R, TRIP590, TWIP940). To account for the micro-damage initiation and evolution as well as macro-crack formation, the stress triaxiality dependent fracture criterion and rate-dependent hardening and ultimate softening behavior were characterized by performing numerical simulations and experiments for the simple tension and V-notch tests. The developed damage model and the characterized mechanical property were incorporated into the FE program ABAQUS/Explicit to perform hole expansion simulations, which showed good agreement with experiments.

Based on combined continuum-fracture mechanics, fracture criterion was utilized to predict impact performance of advanced high-strength steel sheets: 340R and TWIP940. The macro-crack propagation behavior at high stress triaxiality was characterized by V-notch tests while deformation behavior at high strain rate was characterized by simple tension tests with various cross head speeds. The characterized mechanical properties were incorporated into the FE program ABAQUS/Explicit to simulate the charpy impact tests, which showed good agreement with experiments.

The pipes in the outdoor unit of an air conditioner are designed to reduce the vibration effect of the compressor. Three-dimensional structure of the pipe could provide various design choices and the resultant vibration characteristics of the outdoor units. A design program has been developed for an eligible parametric study of pipe design and automatic vibration analysis using commercial software, I-DEAS, and its macro. Optimal design of pipe configuration has been performed using the commercial software, iSIGHT. The optimized design shows 70 percents improvement in the vibration characteristics of the outdoor unit of an air conditioner.

This paper introduces the characteristics of relationship between probabilistic reliability (LOLE; Loss of Load Expectation) and deterministic reliability (SRR; supply reserve rate) for 2008 year in Korea power system. Korea power system has been using the LOLE criterion to determine the adequacy of installed capacity (ICAP) requirement. The criterion is that load shall not exceed the avaliable capacity, on the average, more than five day in ten years. The probabilistic reliability evaluation and production cost simulation program which is called PPHFHT was used in order to obtain the relationship in this paper.

Mechanical behavior in nano-sized structures differs from those in macro sized structures due to surface effect. As the ratio of surface to volume increases, surface effect is not negligible and causes size-dependent mechanical behavior. In order to identify this size effect, atomistic simulations are required; however, it has many limitations because too much computational resource and time are needed. To overcome the restrictions of the atomistic simulations and graft the well-established continuum theories, the continuum model considering surface effect, which is based on the bridging technique between atomistic and continuum simulations, is introduced. Because it reflects the size effect, it is possible to carry out a variety of analysis which is intractable in the atomistic simulations. As a part of the application examples, the homogenization method is applied to micro/nano thin films with porosity and the homogenized elastic coefficients of the nano scale thickness porous films are computed in this paper.

Objectives: This article intends to explore the major documents about inter-sectoral collaboration for physical activity promotion based on new paradigm. Methods: In addition to the documents after 1990s collected through several physical activity related projects of author, additional snowballing exploration has been done. Results: Globally extensive participation of stake-holders and partnership developed were strategically recommended and implementation strategy and good example were provided. In Europe individual, micro-environmental and macro-environmental specific role of major sectors were provided. Nationally series of Australian documents officialized inter-sectoral linkages from early times and Slovenian program showed examples of inter-sectoral evaluation and health indicators. U.S. national physical activity plan showed specific example of 6 guiding principles and 5 overarching strategies among 8 sectors for good inter-sectoral collaboration. In city level, healthy city approach activated. Conclusions: Various specific good examples of intersectoral physical activity collaboration could searched globally, regionally and nationally for application in Korea.

This paper presents Static Synchronous Series Compensator(SSSC) model for power flow study using IPLAN. In the proposed model, SSSC is represented by the equivalent load variation. The equivalent load consists of active power load specified by user and reactive power load which is founded for considering characteristic of SSSC. And this is implemented by IPLAN which is a macro-external program for PSS/E. Using this model, SSSC can be solved in load-flow by just calling the model in PSS/E. The proposed model was applied to a realistic power system for validity test.
