摘要
对于处在平面复杂应力状态下的横力弯曲梁,当引入拉压不同模量后,结构内力计算成为非线性问题;对拉压不同模量横力弯曲梁提出计算假定,推导单元中和轴公式并构造了算法;通过实例计算对比分析不同模量与经典力学相同模量两种方法计算结果的差异,提出对该类结构计算的合理建议以及利用不同模量对结构进行优化的结论.
With regard to transverse bending beam under complex stress state in plane, when different tension and compression modulus is introduced,the pole bending rigidity is a function of internal force so that the calculation of structural internal force becomes nonlinear problem. Calculation supposition is put forward on different modulus of transverse bending beam to deduce unit neutralizing axis formala and construct its algorithm. Through example calculation to compare the difference of such two algorithms as the different modulus and modulus of classical mechanics,reasonable suggestion is pointed out for this kind of calculation and for using different modulus to optimize the structure.
