 principle of energy
 A geometrically attractive and covariant derivation of the balance laws from the principle of energy balance in terms of this stress is presented. From the results of tensile, compression, and three-point bend testing of specimens, the parameters of elasticity and strength for an "equivalent" orthotropic body have been determined on the basis of Bolotin's principle of energy smoothing. Then based on principle of energy equilibrium we propose a global infrared image synthesis model for urban scene, discuss the specific forms for various parts of the scene and compute their surface temperature. We propose to reconcile these apparently contradictory results by combining the virial theorem and a principle of energy partitioning between energy storage elements in a system with dissipation. During this period, Helmoltz (über die Erhaltung der Kraft, 1847) showed that the principle of energy conservation may be applied to living systems. 更多
 This paper presents a new simple way of calculation of the load lateral distribution and lateral diaphragms of the trussed arch btidge of the principle of energy. The calculation is named the elastically supported continuous beam method, which can also be used for lateral strain calculations of bridge structures of other types. 本文利用能量原理导出了桁架拱桥横向分布和横隔梁计算的一般方法——弹性支承连续梁法。它计算简单方便,力学概念清晰,亦可以应用到其它桥梁体系的横向受力计算。 This paper uses the principle of energy to obtain the approximate solutions for the cable-stayed bridges. The method of successive approximation has been applied to the analyses of the actual bridge.

The presented method is suitable for both the electronic computor program and the pocket calculator in analysing bridges. 本文采用能量原理,导出斜拉桥的近似解答,并利用逐次渐近法对一座实际桥梁进行数值计算。计算结果同普通程序的计算和实测值吻合良好。所介绍的计算方法既能适用于计算机程序又能用于袖珍计算器的计算。 The fundamental principles for stress and internal force redistribution due to creep in composite structure with steel beam and concrete deck are described and discussed in this paper.
