外力系的英文
external-force system
例句与用法
- For the model of interface cracks originating at lining edge , the added force at crack tip can be replaced by expression including dynamic stress intensity factor
对于界面圆环形衬砌的裂纹问题，裂纹尖端点的附加外力系可以代换成动应力强度因子。 - Finally , a series of fredholm integral equations of first kind for determining the unknown forces can be set up through continuity conditions that are expressed in terms of the green ' s function , finally the integral equations can be transformed into a series of algebraic equations based on the direct - discrete method and solved numerically
利用green函数写出界面位移连续条件，建立求解未知外力系的第一类fredholm积分方程组，采用直接离散的方法将定解积分方程组转化为代数方程组进行求解。本文的具体工作如下： 1 - The model of the problem is composed of two half spaces with half circular lining inclusion . horizontal surfaces of the half spaces are loaded with undetermined anti - plane force in order to satisfy continuity conditions at linking section , or with some certain forces to appear cracks . a series of fredholm integral equations of the first kind for determining the unknown forces can be set up through continuity conditions that expressed by using of the green " function
然后将问题的模型视为“契合”问题，即将其剖分为两个含半圆环形衬砌的弹性半空间，分别在其剖分面上加置未知的出平面荷载，并在欲出现裂纹位置加置出平面反力使之产生裂纹，接下去利用green函数表示出界面连续条件，建立决定待解外力系的第一类fredholm积分方程组。
