| 摘 要： | 考虑面内受单向拉伸载荷作用，研究复合材料对称角铺设［±θ］s矩形层合板层间应力特性。设置单层板为线弹性正交异性材料，应用商业有限元软件(ANSYS)中三维实体单元Solid46进行几何建模和数值分析。给出了典型对称角铺设层合板［±25］s层间应力沿边界的分布规律。结果显示：角点处层间正应力达到最大；自由边处层间剪应力较高，角点处该剪应力降低。并给出了铺层偏轴角θ对层间应力的影响，得出层间最大应力随铺层角度的变化规律。 |

| Abstract： | The paper focuses on the investigation of interlaminar stress characteristics of the symmetric angle-ply laminated rectangular plates ［±θ ］s under uniaxial tensile loading. 3D solid element Solid46 is used in the commercial finite element software ANSYS for establishing geometric modeling and numerical analysis with linear-elastic anisotropic assumption in single ply. The interlaminar stress distribution near the edge of the typical symmetric angle-ply laminated plates ［±25］s is discussed. The results show that the normal stress is maximum at corner points, while shear stress is relatively high at free edge and decreases at corner points. The effect of off-axis angle. on interlaminar stress is studied finally, and the relationship between maximum interlaminar stress and layer angle is achieved. |
