摘要
用非局部线弹性理论，研究了正交各向异性半无限大复合材料的线性分布载荷作用问题，并计算出应力场和位移场的非局部理论解．结果证明：当考虑微结构的相互作用时，非局部应力的解答在集中力作用下的奇异性不存在；当内部特征尺度趋于零时，应力场的非局部解答即为经典解答，而位移场与经典解相一致．
In this paper, the problem of the orthtropic half-infinite composite materials sub.. jected to line force is studied by using nonlocal line elasticity theory. The nonlocal stresses, displacements and nonlocal concetrated force are calculated. The results show that the classical stresses singularity at the point of the concentrated force are not present in nonlocal stresses when the interaction of the microstructures is considered, and the nonlocal stresses revert to the classi- cal solution as the internal characteristic length tends to zero, but the nonlocal displacements fields coincide with the classical counterparts.
