摘要
分析工程中对于由多种材料组合而成的一般截面形状平面曲梁在载荷作用下的强度问题。在截面形状不变的假设基础上，导出了其正应力的计算公式。作为特殊情况，该梁在对称弯曲时的相应公式也可以从上述公式得到。
In orderto solvethe strength problem of plane curved beams of generalsectionalshape combined with several materials under the loads ,the calculation formulas of normal stresses are derived on the basis of the as sumption of unchangable sectional shape .As a special case ,the corresponding stress formulas may be obtained from above - mentionedformulasin the symmetry bending ofthe beams.Inthe end ,a numericalexampleis given .
