A Study on Warp Tension of a Tricot Machine
Journal of the Textile Machinary Society, 1958 研究目的テンションばねを用いた張力制御回路において, 入力を糸の伸びとしたとき, 張力の近似計算に必要な諸条件を設定するとともに, 具体的な一例として積極的経糸送出装置を有するトリコット機の経糸張力と伸長量および回転数の関係を解析し, 良好な張力制御条件を検討する.研究結果(1) 一般に纎維機械で操作中の糸の張力を計算する場合は糸の力学的モデルを二つ設定し, それぞれ動的および静的な入力に対応させ, 動的入力 (振動的入力) に対応するモデルに1個のVoigtモデルを用い, 数値計算に当って従来糸の粘弾性的な実験に供せられる短い長さの糸について, 得られている動的実験データを使用することは有益な近似方法と考えられる.(2) (1 ...

Proposed Algorithm for Warp Direction Checking in Tensioned Fabric Structures
International Journal of Scientific Research in Knowledge, 2013 Mesh generation of tensioned fabric structure is needed before form-finding. The sequence of defining the mesh of a surface must ensure that the warp and fill direction of the fabric material used in the model is properly represented due to orthotropic nature of fabric material.

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Computer Simulation of Warp Tension on a Weaving Machine
Sen'i Kikai Gakkaishi (Journal of the Textile Machinery Society of Japan), 2003 This paper investigates about the simulation of warp tension variation in a weaving machine, based on mathematical and mechanical equations. To perform simulation, a differential equation system was formed and solved by numerical method. The results shown as the curves of warp tension variations and back rail oscillation of the loom were compared with ...
