论Timoshenko总势能的不完备性
ON THE IMPERFECTION OF TIMOSHENKO'S GENERAL POTENTIAL ENERGY EQUATION
-
摘要: 运用能量变分,导出梁弯扭屈曲问题计算的势能.这一势能不是梁的全部势能,与Timoshenko能量法中的总势能不同.文中讨论Timoshenko总势能,指出它的不完备性及应用的局限性.Abstract: Based on the principle of the variation of energy, the potential energy for the lateral-torsional buckling of beams is obtained. It is not the total energy which is different from Timoshenko's general potential energy. Some aspects of Timoshenko's equation are discussed. Its imperfection and limitation of application are pointed out.
