Independent metrical evidence tells us that heavy rimes may carry inherent stress.
      
In contrast, in S-languages, regular rimes do not carry inherent stress; instead, only those syllables that are assigned stress by rule can keep their underlying tones and hence head a multisyllabic tonal domain.

This paper proposes a method for analyzing the nature of singularity at an elastic crack-tip. According to the Muskhelishvili's exact solution of an elastic elliptical hole, the variations of the stress fields of different crack-tips are determined as the tip of the elliptic-crack model changing from a blunt tip to a sharp tip. The stress field at the blunt tip is represented by a function of several variables. The different limits of this function describe the nature of singularity at the crack-tip. With...

This paper proposes a method for analyzing the nature of singularity at an elastic crack-tip. According to the Muskhelishvili's exact solution of an elastic elliptical hole, the variations of the stress fields of different crack-tips are determined as the tip of the elliptic-crack model changing from a blunt tip to a sharp tip. The stress field at the blunt tip is represented by a function of several variables. The different limits of this function describe the nature of singularity at the crack-tip. With this method, the states of stresses and boundary conditions both at the blunt crack-tip and sharp crack-tip are discussed. In this paper, time stresses at the crack-tip are divided into two different kinds: i. e. intrinsic stress and approaching stress. The intrinsic stress is the stress that satisfies all the boundary conditions, while the approaching stress is tile stress that approaches to the crack-tip during the process of degenerating from an elliptic crack to a crack with Sharp tip. By use of the concept of intrinsic stress and approaching stress, the nature of the singularity of the stress field at the crack-tip can be analyzed, and the cause for the formation of tie "Sub-crack" during the blunting process of the sharp tip can be explained.

本文由弹性平面椭圆孔的精确解出发,用一个椭圆裂纹模型(钝角裂纹模型)退化到无限细裂纹(尖角裂纹模型)的方法讨论了平面裂纹尖端应力场的奇异性质。文中将裂纹尖端附近的应力场表达为一个多变量函数。然后,由各种不同的途径趋向裂纹尖点,从而求得了多重极限。分析表明,这一多变量函数的全面极限并不存在,而多重极限是存在的,但是各不相等。由这些多重极限的变化可以将裂纹尖点的应力分为两种类型:固有应力和趋近应力。其中固有应力是椭圆裂纹模型尖端处固有的应力,这些应力全部满足边界条件;趋近应力是当椭圆裂纹退化到无限细裂纹时所产生的应力场。由趋近应力和固有应力的变化就可以说明裂纹尖点应力场的奇异性质,并可解释“次裂纹”形成的原因。 本文根据对裂纹尖端应力场奇异性质的分析结果讨论了Westergaard-Irwin应力强度因子理论的近似性和局限性,并为应用钝角裂纹模型建立起来的广义应力强度因子理论[9]的裂纹尖端应力场计算提供了一种分析方法。

Bulge buns are easily occurred when concrete is filled into a stitching plate of concrete-filled-steel arch bridge by the pressure pump. To determine the stresses in the bulge buns is important for engineering. As their locations are of accidental, the determination is hardly to be done by usual method.

钢管混凝土拱桥的缀板在灌注混凝土的泵送施工中极易产生鼓包现象,鼓包处的应力测试对工程处置极为重要,但因其位置和大小有一定的偶然性,难以采用预置传感器方法进行.需采用固有应力的测试方法.本文提出了用局部微损的小盲孔表面应力释放测试方法进行钢管混凝土拱桥缀板鼓包应力的思路.并结合工程实例研究了方法实施过程中遇到的若干问题,如方案的选择、测试的理论依据、实施过程和对结果的解释等问题.
