Elasto-Plasticity Behavior of Type 5000 and 6000 Aluminum Alloy Sheets and Its Constitutive Modeling
Shohei TAMURA,Satoshi SUMIKAWA,Hiroshi HAMASAKI,Takeshi UEMORI,Fusahito YOSHIDA 한국소성가공학회 2010 기타자료 Vol.2010 No.6
To examine the deformation characteristic of type 5000 and 6000 aluminum alloy sheets, uniaxial tension, biaxial stretching and in-plane cyclic tension-compression experiments were performed, and from these, r-values (r?, r45 and r90), yield loci and cyclic stress-strain responses were obtained. For the accurate description of anisotropies of the materials, high-ordered anisotropic yield functions, such as Gotoh’s biquadratic yield function and Barlat’s Yld2000-2d, are necessary. Furthermore, for the simulation of cyclic behavior, an advanced kinematic hardening model, such as Yoshida-Uemori model (Y-U model), should be employed. The effect of the selection of material models on the accuracy of the springback prediction was discussed by performing hat bending FE simulation using several yield functions and two types of hardening laws (the isotropic hardening model and Y-U model)

Mindfulness-based Interventions and effectiveness for Nurses: A Systematic Review Protocol
IIKURA Atsumi,TAMURA Haruka,MIYAMOTO Shohei 한국간호과학회 2021 한국간호과학회 학술대회 Vol.2021 No.10
Aims: Mindfulness is a state of focusing the mind on the “now” and is recognized for its effectiveness in activating the brain and reducing stress. Mindfulness programs have been adopted in various workplaces in recent years, and interventions have been provided for nurses. The purpose of this study is to confirm the actual mindfulness intervention and its effects on nurses and to clarify the circumstances by the description of the intervention, outcomes, and type of bias. Methods: We conducted a systematic review of randomized and non-randomized controlled trials published until June 2021. This search string will be used to search Web of Science, PubMed, Science Direct, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), CiNii, Ichu-shi, and J-STAGE. The selected papers will be screened by title and abstract according to the inclusion and exclusion criteria by two independent reviewers. Three individual reviewers will screen the full-text papers using inclusion and exclusion criteria. After the full-text screening, articles undergo data extraction and risk of bias. The extracted data will be synthesized narratively. Discussion and Registration: This article presents the protocol for a systematic review describing the methods and effects of a mindfulness intervention for nurses. The results will systematically organize the mindfulness interventions that have been provided to nurses and will be useful in the future for implementing mindfulness in practice. This protocol is under submission in the PROSPERO database.
