Buckling of Rectangular Composite Pipes under Torsion

Autor: Atsushi Takano, Ryo Mizukami, Ryuta Kitamura

Publikováno v: Applied Sciences, Vol 11, Iss 3, p 1342 (2021)

The numerical buckling load of rectangular composite pipes under torsional load was derived by using the energy method. The authors found no available simple design method or chart for the buckling loads of rectangular composite pipes, which are ofte

Buckling Test of Composite Cylindrical Shells with Large Radius Thickness Ratio

Autor: Atsushi Takano, Ryuta Kitamura, Takuma Masai, Jingxuan Bao

Publikováno v: Applied Sciences, Vol 11, Iss 2, p 854 (2021)

A buckling test of composite cylindrical shells with a radius–thickness ratio (r/t) = 893 under axial compression was conducted to investigate the effects of the radius–thickness ratio (r/t). It is known that the buckling load of cylinders shows

Effect of Lap Length and Stiffness of Peel-Stop Fasteners in Single Lap Joints

Autor: Atsushi Takano, Chao Li, Ryuta Kitamura

Publikováno v: Applied Sciences, Vol 11, Iss 3, p 1086 (2021)

Strength tests on single lap joints with one adhesive (AV138/HV998) and one adhesive layer thickness (0.5 mm), three peel stoppers (brass bolt, nylon bolt and steel pin), and four lap lengths (12.5 mm, 25 mm, 40 mm and 100 mm) were conducted to inves

Damage behavior in CFRP laminates containing fiber discontinuities of different sizes

Autor: Hayato NAKATANI, Yu NAGATA, Ryuta KITAMURA, Akira MATSUBA, Yousuke KOUNO, Shinji OGIHARA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 81, Iss 831, Pp 15-00226-15-00226 (2015)

Mechanical properties and damage onset stress in 24 or 25-ply unidirectional CFRP laminates that contain different thicknesses and gap lengths of fiber discontinuity are investigated by tensile testing and analytical model. Same damage behavior, as w

Verification of damage model of ceramic matrix composites and analysis of cyclic deformation behavior

Autor: Ryuta KITAMURA, Koichi GODA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 80, Iss 812, Pp SMM0080-SMM0080 (2014)

Ceramics are excellent in heat, abrasion and corrosion resistances, but their strength reliability for structural materials is not enough due to their brittle nature. On the other hand, ceramic matrix composites (CMCs) reinforced with ceramic fibers

Influence of Inorganic Solid Particles in the Formation and Stability of Crude Oil Emulsion

Autor: Tokima Hattori, Xingjuan Hao, Mai Shimokawara, Yoshitake Kato, Ryuta Kitamura, Yogarajah Elakneswaran

Publikováno v: Day 3 Fri, March 03, 2023.

Water-in-oil (W/O) emulsion could be formed during the transportation, refining, and storage of crude oils. In the stockpiling tanks, the emulsion and sludge formation were observed by storing of crude oils for a long period of time and cleaning of t
