Interlaminar Stresses of a Laminated Composite Bar under Bending (Ⅰ)

摘要: 一矩形横截面的叠层复合材料杆,由以一种材料为中心部分,及另一种材料的上下两相同的盖板所组成.各等于P的压力和张力,均匀分布在上下盖板的两端.它们形成两力偶使杆弯曲.本文将探讨层间应力,以表明力是怎样通过胶合面而传递的.Abstract: A laminated composite bar of rectangular cross section consists of a milde portion of one material and upper and lower identeal cover plates of another muterial. Uniformly distributed compressive and tensile forces each equal to p are acting respectively at the ends of the upper and lower cover plates. They form conples at both ends of the bar. Our aim is to find the interlaminar stresses or how the forces are transmitted through the glued sarfaces.
