湿熱環境下でのき裂を有する円柱の応力解析と連成効果 菅野, 良弘 村木, 剛尚 中馬, 康晴 奥田, 昭 社団法人日本機械学会 本文データは学協会の許諾に基づきCiNiiから複製したものである Hygrothermoelasticity Crack Problem Moisture and Temperature Coupling Effect Stress Intensity Factor Circular Cylinder Composite Material In this paper, an analytical solution is presented for stress intensity factor of a solid circular cylinder with an edge crack subjected to transient hygrothermal loading on the lateral surface. It is assumed that the coupled diffusion problem of temperature and moisture in the cylinder over a short time can be analyzed by neglecting the hygrothermal disturbance near the crack tip. The associated plane-strain hygrothermal stress problem is solved by the use of Tweed and Rooke's solution for a pure elastic problem in a circular cylinder with the same crack. Numerical calculations are carried out for the stress intensity factor at the crack tip in the circular cylinder made of T300/5208(graphite/epoxy) composite material. The effect of crack length and coupling of temperature and moisture fields on the stress intensity factor are quantitatively estimated under various thermal and hygrometric loading conditions. 社団法人日本機械学会 1994-01-01 jpn journal article VoR https://iwate-u.repo.nii.ac.jp/records/9722 http://ci.nii.ac.jp/naid/110002371919/ 0387-5008 湿熱環境下でのき裂を有する円柱の応力解析と連成効果 60 574 1357 1364 https://iwate-u.repo.nii.ac.jp/record/9722/files/tjsmea-v60n574p1357-1364.pdf application/pdf 596.1 kB 2016-11-14
