| 摘 要： | 拉压不同模量的材料在工程中应用很广,特别是近几年发展起来的复合材料都具有明显的拉压不同模量性质.本文对复杂应力状态下不同模量连续梁提出了中性轴判断定理,并用分段积分方法推导出不同模量结构的中性层计算表达式及应力的解析解.通过对实例的计算及分析,得出不同模量与经典力相同模量两种方法在结构应力计算上的差异,最后提出对该类结...

| Abstract: | Materials with different modulus in tension and compression have a wide application in engineering practice,especially the composite materials developed in recent years,which have properties of different tension-compression modulus.The determinant theorem of neutral axis for continuous beam with different modulusunder complex stress was suggests,and the formulae of neutral axis as well as the analytical solution of stress for structures with different modulus by segmental integral method were deduced.Some e... |
