[領域]彈性力學 (題目相關領域) [來源]課堂作業 (課本習題、考古題、參考書...) [題目]Discuss the solution of the elastostatic problem for the case where τ下標(xx) = τ(yy) = τ(zz) = -p + ρgz τ(xy) = τ(yz) = τ(zx) = 0 This state of stress corresponds to that found in a body immersed in a fluid whose density is the same as that of the body,where p is the pressure of the fluid at the level of the origin of coordinates. [瓶頸] (寫寫自己的想法，方便大家為你解答) 這是這學期修彈力，老師出的作業。只知道這是elastostatic problem 不過為什麼τ下標(xx) = τ(yy) = τ(zz) = -p + ρgz 如果是τ(zz) = -p + ρgz我還知道 不過不知道為什麼τ(xx) = τ(yy) = τ(zz) 完全不知道從何開頭。 參考書籍有 (目前手邊有的) 錢偉長的彈性力學 advanced strength & applied elasticity Ansel C. Ugural Saul K. Fenster Elasticity Martin H. Sadd Introduction of solid Mechanics Y.C.Fung 不過都找不到頭緒，還望板上先進指點指點。 -- 痛苦和驕傲 這一生都要擁有 --
