Comparative study of plasticity models for concrete material by using different criteria including Hsieh-Ting-Chen criterion
No full textThe purpose of this study is to investigate nonlinear behavior of reinforced concrete (RC) structures with the plasticity modeling. For this aim a nonlinear finite element analysis program is coded in MATLAB. This program contains several yield criteria and stress-strain relationship for compression and tension behavior of concrete. In this paper, the well-known criteria, Drucker-Prager, von Mises, and a new criterion, Hsieh-Ting-Chen, are taken into account. The elastic-perfectly plastic and Park-Paulay stress-strain relationships in compression behavior and tension stiffening in tension behavior of concrete are used with four different yield criteria mentioned above. It is concluded that the proposed models are in good agreement with the experimental and analytical results taken from the literature. It is also concluded that the coded program, the proposed models, and Hsieh-Ting-Chen criterion can be effectively used in the nonlinear analysis of reinforced concrete beams. (C) 2009 Elsevier Ltd.

Sintering effects and hydrothermal ageing behaviour of Yttria-stabilised zirconia with MnO2 doping / Ting Chen Hunt
Get PDFYSZ ceramics has outstanding mechanical properties and has been used for many engineering applications. However, a major drawback of this ceramic is the undesirable ageing-induced tetragonal to monoclinic phase transformation resulting in properties deterioration when exposed to steam environment. In most cases for commercial YSZ powders, high sintering temperature or/and long holding time are required via the common pressureless sintering approach which leads to grain growth exceeding the critical size that triggered low temperature degradation consequently lead to structural failure. One possible approach to suppress the excessive grain growth of YSZ is conducting low temperature sintering by adding small amount of MnO2 as sintering aid. The present work investigate the influence of low temperature sintering, focusing on varying sintering holding times on the mechanical properties, microstructure and low temperature degradation behavior of undoped and MnO2 (0.5 & 1.0 wt%) doped YSZ ceramics were investigated. Green samples were sintered at temperatures ranging from 1100 to 1250 ºC at varying holding times from 12 min to 480 min. The sintered bodies were characterized in terms of bulk density, fracture toughness, Vickers hardness, phase stability and microstructure evolution. Hydrothermal ageing tests up to 120 hr were conducted at 180 ºC with pressure 10 bar in an autoclave. The amount of monoclinic ZrO2 on the aged surface was measured by X-ray diffraction (XRD). Another group of undoped YSZ samples were pressureless sintered at higher temperatures (1200 to 1500 ºC) with standard heating rate 10 ºC/min and holding time, 120 min were prepared for comparison purpose. Densification and mechanical properties of YSZ ceramics were improved even at low sintering temperature when doped with MnO2 additive. The results indicated the relative density of above 95 %, Vickers hardness of 14 GPa and fracture toughness of 5 MPam1/2 were obtained when sintered at low sintering temperature of 1150 ºC, holding time 480 min or 1250 ºC, 12 min respectively for 1.0 wt% MnO2-doped YSZ ceramics. Grain growth at low sintering temperature was marginal and the average grain size of all samples ranged between 0.14 to 0.28 μm. The results indicated that the grain growth kinetics was influenced mainly by the sintering temperature and not by the sintering holding time. The low temperature degradation (LTD) experiment conducted in superheated steam for 120 hr indicated that all the undoped YSZ ceramics via standard heating profile and temperature < 1300 ºC showed no the monoclinic phase which attributed to the lower grain size and homogeneous distribution of yttria in the tetragonal grains. However, small traces of monoclinic phase was formed in MnO2-doped YSZ ceramics even at low sintering temperature, 1200 & 1250 ºC and the rate of transformation was increased with higher amount of dopant and longer sintering holding time beyond 120 min which could be attributed destabilising of tetragonal grain as the result of redistribution of yttria in the grain. Ageing mechanism was subsequently proposed to account for the LTD behaviour of the YSZ ceramics

Hsiang-Ting Chen
Abstract
The purpose of this research was to explore the transpersonal experience in helping others through one Tzu-Chi people. This is a qualitative research. By using semi-structured interviewing guidances, the researcher performed one-by-one in-depth interviews twice, each time about two hours. Latter, the research used Moustakas’s phenomenological research methods to analyze data and perform results. The main results of this research are as follows :
1. In the co-researcher’s transpersonal experience, the wish of learning Kuan-Yin Bodhisattva’s spirits to love and benefit others guided all her movements.
2. Master Cheng-Yen presents mercy and wisdom as Kuan-Yin Bodhisattva. Cheng-Yen’s mercy touched the co-researcher, and wisdom helped her a lot.
3. Tzu-Chi people support and grow each other. Through their team-work, the co-researcher’s goal of helping others could be fulfilled.
4. In helping others, the co-researcher obtained growth and changes ---- the meaning and value of live been promoted. This supported her to help others continuously.
5. The co-researcher’s positive, diligent and modest learning attitude and serious, responsible working manners were the important factors which made the transcendence possible.
From above results, there are some important discoveries as follows :
1. In the transpersonal experience, self-growth and the transpersonal movement of helping others complement each other.
2. During the transpersonal experience, the self-autonomy guides person’s movement.
3. By helping people, individual’s body become more healthy, and his mind become more mercy, lighter and more abundant. The changes include body and mentality.
4. The factors which effects the happening of transpersonal experience could be summed up as below：believe factor, context factor and personal characteristics.
According to the results and discoveries of this research, the researcher provides some concrete suggestions in practice and future researches.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
