The new measurement theory is deduced in detail by using elasticity theory . a new approach is provided to measure the residual stress in the thick plate 运用弹性力学理论对该方法进行了详细推导,为厚板内部残余应力测试提供了一条新途径。
First , mathematical expressions for hoop strain based on linear elasticity theory and deformation plasticity theory , and thus diametral strain is derived 模型推导过程是:首先根据线性弹性理论和变形塑性理论推导出周向应变的数学表达式,进而导出径向应变。
In chapter 2 , the partial differential equations of heat transfer and the basic equations of heat elasticity theory as well as the solution with the finite element method have been explained 第2章阐述了热传导的偏微分方程和热弹性理论的基本方程以及用有限元法进行的求解。
The raft rigidity directly affected by the dimensions of the board , however , were neglected in the traditional analyzing of substratum settlement except of the elasticity theory method 除弹性理论法外,其它常用的设计和分析方法几乎都没有考虑筏板刚度对下卧层沉降的调节作用。
It can be concluded that difference between tensile modulus and compressive modulus is an important property of soil and the solution of elasticity theory with different modulus in tension and compression is necessary and reasonable 可以认为,拉压模量不同是土的重要性质,拉压模量不同弹性理论解答的提出是合理的。
