Structural Concrete, EarlyView.Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Some Improvements in Elastoplastic Friction Compensator
SICE Journal of Control, Measurement, and System Integration, 2017 For robotic joints with compliant transmissions, Mahvash and Okamura have proposed a friction compensator based on an elastoplastic friction model. One drawback of the compensator is that the compensator continues producing non-zero output force in the ...

AN AVERAGING METHOD OF ELASTOPLASTIC BEHAVIOR OF COMPOSITES AND POLYCRYSTALLINE METALS
Doboku Gakkai Ronbunshuu A, 2008 複合材料等の非均質材料の巨視的挙動の解析的な予測法に，森・田中理論に基づいた手法やHashin-Shtrikmanの上下界手法等があり，微視的な幾何条件とつり合いが考慮されている．著者らは弾性の場合に，古典的手法から上述の手法を包含し，かつさらに応用できる予測法を提案した．それは森・田中の考え方を3相材料に適用した上で，母材の体積比率を零にすることによって得られる2 相材料の予測手法で，従来の手法よりも実験値をより精度良く予測し，またHillのself-consistent解と同じ予測特性を持つことが明らかにされてきた．ここではその手法を弾塑性体に適用し，一般的な載荷状態で最適な母材の材料パラメータを選択する方法を提案する．そして，その予測結果を既存の実験値や他の解析結果等と比較し ...
