[领域]弹性力学 (题目相关领域) [来源]课堂作业 (课本习题、考古题、参考书...) [题目]Discuss the solution of the elastostatic problem for the case where τ下标(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. [瓶颈] (写写自己的想法，方便大家为你解答) 这是这学期修弹力，老师出的作业。只知道这是elastostatic problem 不过为什麽τ下标(xx) = τ(yy) = τ(zz) = -p + ρgz 如果是τ(zz) = -p + ρgz我还知道 不过不知道为什麽τ(xx) = τ(yy) = τ(zz) 完全不知道从何开头。 参考书籍有 (目前手边有的) 钱伟长的弹性力学 advanced strength & applied elasticity Ansel C. Ugural Saul K. Fenster Elasticity Martin H. Sadd Introduction of solid Mechanics Y.C.Fung 不过都找不到头绪，还望板上先进指点指点。 -- 痛苦和骄傲 这一生都要拥有 --
