摘要
Abstract
In exploring the stress between the fiber and the matrix during tensioning and compression,the theo-retical mathematical equations for axial and shear forces are derived based on the Cox shear lag model.In the deriva-tion process,the radial force is considered,while the stress-transferring process between the fiber and the matrix needs to be realized through shear stress.Finally,the axial force is solved,and the distribution of the axial force and shear force is plotted and analyzed in detail.It was eventually found that the maximum shear stress was reduced by 5.25％in the presence of radial forces,and the maximum axial force was increased by 3.76％.Also,during the stretching process,the maximum shear stress was found to occur at the ends of the fiber,while the maximum axial force appeared at the center of the fiber.关键词
