  thicker plate
The material with thin alpha plates more rapidly forms equiaxed alpha grains separated by beta phase, while the material with a thicker plate structure exhibits more alpha/alpha boundaries after deformation and annealing.
      
It was found that material with an initial thin alpha plate structure (thickness - 3.4 ?m) breaks up at a lower critical strain than a material with a thicker plate morphology (thickness ? 6 μm).
      
The toughness of the fully hardened 4140 was also compared with the toughness measured earlier on a 25 pct thicker plate that did not through-harden.
      
In this case, the specific rotation of the plane of polarization along the optic axis is 68.2 degrees/mm for a thicker plate and 83.3 degrees/mm for a thin plate.
      
Regarding the effect of biaxiality on crack tip stress triaxiality, it is found that such effect is more pronounced for a thicker plate.

In this paper, the solution of an infinite elastic thick plate under the action of nonsymmetrical normal and tangential loads on its upper and lower surfaces has been obtained by using the Fourier transform to the stress function. Successively the author discussed the calculation of the multi-layer foundation resting on a rigid rock base. Two concret examples have been calculated, i.e. i) an isotropic elastic layer having the depth h under rectangular uniform pressure; ii) two-layer soil under the same...

In this paper, the solution of an infinite elastic thick plate under the action of nonsymmetrical normal and tangential loads on its upper and lower surfaces has been obtained by using the Fourier transform to the stress function. Successively the author discussed the calculation of the multi-layer foundation resting on a rigid rock base. Two concret examples have been calculated, i.e. i) an isotropic elastic layer having the depth h under rectangular uniform pressure; ii) two-layer soil under the same uniform pressure. The special case due to a concentrated load in the first example we obtain the same result as appeared in the reference[6]and the second example, by using the method of numerical calculation, the result of maximum stress on the rigid rock base is obtained about 4% than that of the reference[6].

A mathematical theory of thick plate is established on another mechanical hypothesis differed from a thin plate. In this paper a statical analysis for thick plate is given. For an arbitrary plate of polygonal shape with simply supported edges it is shown that the solution of thick plate can be "expressed explicitly by that of thin plate. It is then found that the shear forces of thick plate in the Reissner model are identical with those of thin plate, while in the washizu model of thick plate the shear forces as well as bending moments and angular rotations all are same as the classical thin plate tbeory.

厚板的数学理论是建立在与薄板不同的力学假定的基础上的。本文分析了厚板与薄板之间静力学方面的关系。对于任意的简支多边形板,得到了厚板解通过薄板解的显式表达式,从而证明了:Reissner模型的厚板解与薄板解具有相同的剪力,但弯矩、转角、挠度有差别;而washizu模型的厚板解则与薄板解不仅剪力相同,连弯矩与转角亦相同,只是挠度有差别。

Introducing a displacement function Φ, the solution of the differential equation of motion in elasticity is then reduced as to determine such a displacement function Φ satisfying a six order differential equation. Therefore,the solution may be obtained by means of separation of variables and as a consequence the formulas of displacements and stress components are given in the presentation of cartesian coordinates. The constants in these formulas are determined according as the load-up condition of a rectangularly...

Introducing a displacement function Φ, the solution of the differential equation of motion in elasticity is then reduced as to determine such a displacement function Φ satisfying a six order differential equation. Therefore,the solution may be obtained by means of separation of variables and as a consequence the formulas of displacements and stress components are given in the presentation of cartesian coordinates. The constants in these formulas are determined according as the load-up condition of a rectangularly thick plate simply supported on which the periodic load acting distributively or concentra-tively. As for the frequency equation of vibration, it has been formulated according to the state that the surfaces of plate being free from loading. Illustrating with an example of square plate the fundamental frequencies of plates of various thickness are computed and compared with the results by engineering theory of thin plates.

本文从弹性力学运动微分方程出发,引入了一个位移函数φ_r把运动方程的求解问题变成找位移函数φ满足一个六阶微分方程,用分离变量法求得了方程用直角座标表示的解,从而求得了位移和应力的表达式。根据简支矩形厚板受分布的或集中的周期力作用的条件定出了各常数,又根据板面外载荷为零的条件建立了简支矩形厚板的自振频率方程式。以正方形板为例对不同厚度的板求得了基本频率,并与由工程理论所得的薄板振动公式计算结果作了比较。
