| Abstract: | According to the fundamental theory of elasticity , the Newmann problem of the rectangular region with longitudinal shear load is set up ;The Fourier series of load is given by using generalized step function and the displacement formula of the longitudinal shear problem is derived . In this paper , the expressions of the displacement and the shear stress are presented according to the possible form of the longitudinal load. This solution is of some academic and practical significance. |
