Abstract：The internal friction of foamed aluminium in acoustic frequency has been studied. It shows that the internal friction of foamed aluminium enhanced in comparison with that of massive aluminium, the internal friction decreased when frequency was raised and 收稿日期: 1997-04-25      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 刘长松 朱震刚 韩福生 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y1997/V11/I2/153 1.S.C.Cowin, J、W.Nunziato,J.Elast. 13(2), 125(1983) 2.P.Puri, S.C.Cowin,J.Elast 15(2), 167(1985) 3.J.P.Drolet, Int J.Power Met.Power Tech, 13(3),222(1977) 4.A.S.Nowick, B.S.Berry, Anelastic Relaxation in Crystalline Solids(New York and London, Academic Press, 1972)p.595 5.余兴泉,何德坪机械工程材料18(2),26(199) 6.M.A.Goodman, S.C.Cowin, Arch.Ration.Mech.Anal. 44,249(1972) 7.J TJekines,J.Appl.Mech. 42,603(1975) 8.R.D.Mindlin,Arch.Ration.Mech.Anal.16,51(1964) 9.R.A.Toupin, Arch.Ration.Mech.Anal. 17,85(1964) 10.J.W.Nunziato, E.K.Walsh, J.Appl.Mech. 44,559 (1977) 11.J.W.Nunziato,S.C.Cowin,Arch.Ration.Mech.Anal.72,175(197) 12.J.W Nunziato, E.K.Walsh, Arch.Ration.
