周期应力平面弹性理论中的一点注记 A REMARK ON PLANE ELASTICITY WITH PFRIODIC STRESSES 路见可 Lu Jianke first-author <正> 我们在[1]中曾经证明:在平面弹性系统中,如果应力已知是周期的(且设有界),则其相应位移必定是准周期的,即每经过一周期,位移要增加一常数;因此并得出周期应力第一基本问题的一般提法。这里我们要指出,其逆也成立,即,我们有: In this note, we state and prove a theorem in the theory of plane elasticity with periodicity which shows that the stresses must be periodic if the displacements are quasi-periodic. 1980-03-01 2021-04-01 3
