Elastoplastic analysis of mises metal by return-mapping algorithm for extended subloading surface model

The extended subloading surface model is capable of representing not only monotonic but also cyclic loading behaviors accurately. The various return-mapping methods have been adopted to for the elastoplastic deformation analysis in FEM incorporating the subloading surface model. However, the past algorithms based on the expansion of the subloading surface is inapplicable to the cyclic loading behaviors. Then, the rigorous complete integration algorithm for Mises metal is adopted in this study. Additionally, it is implemented into the FEM software ABAQUS through the user-subroutine UMAT. The numerical calculations are performed for the forward and inverse loading processes by use of the proposed and the past implicit algorithms. A more accurate elastoplastic deformation analyses can be conducted by the proposed algorithm. Thus, it may be stated that the accurate numerical solution can be attained by adopting the proposed return-mapping algorithm for the general loading process

Characteristics of hydrophobicity loss on silicone rubber surface during a dynamic drop test with direct current voltage application

Dynamic drop test for studying the temporal lowering of hydrophobicity on the surface of silicone rubber with direct current voltage application was carried out. In this study, we evaluated the influence of the temporal lowering of hydrophobicity under various conductivities and dropping rates for water droplets. As a result, it was found that the dropping rate and the conductivity of water droplets greatly influenced the hydrophobicity loss time on the surface of silicone rubber

がんピアサポーター養成研修前後における受講生のピアサポーター像の変化

がんピアサポーター養成研修前後の受講生が描くピアサポーター像を明らかにし、研修の成果と課題を検討することを目的に質的に分析した。研修前後とも【コミュニケーション技術】【ピアサポーターとしての心構え】【ピアサポーターとしての存在意義】【期待される社会的役割】の4カテゴリーに分類された。研修後はがんピアサポーターに関する内容の多様化、および表現の具現化が見られた。がんピアサポーターに求められる知識や技術、対等な立場で共に考える姿勢、ピアサポーターの自覚と責務が醸成され、研修成果を得たと考えられる。今後は最新のがん知識を取り入れたカリキュラムの更新、受講生への心理的支援の必要性が示唆された
