| 摘 要： | 锥形杆在拉(压)、扭、弯时,平面假设不成立,严格地说,用材料力学的方法给出的应力公式不能用,而应该根据弹性理论给出其应力的计算公式.本文就锥形杆在拉压与扭转以及锥形梁在集中力作用下弯曲时,分别用材料力学和弹性力学的方法给出应力公式并加以讨论,同时对材料力学给出的结果及误差进行分析.

| Abstract: | Planar hypothesis seems not tenable for tampered objects like tampered rod, tampered beam. Errors are therefore often made in the application of conventional stress for mula to calculate both normal and shear stress a tampered object receives on its cross section. A Stress formula,based on both mechanics of materials and mechanics of elasticity,has been introduced to calculate stress when a tampered rod is drawn or twisted and when a tarn pered beam, acted by a centralized force bends. Aiso analysis has been made of calculated stress and errors according to mechanics of materials. |
