A state of stress should always be described as triaxial since any body is three-dimensional . 因为任何物体都是三维的,故应力状态总应按三向来讨论。
In two and three dimensions the yield limit is reached when a certain function of all the stress components reaches a fixed value . 在二维或三维的情况下,当所有应力分量的某个函数达到某一固定值时可达到屈服极限。
The curve should be three-dimensional one, with the high point in the center and curved lines radiating in all directions, somewhat as streamers from a maypole . 曲线应该是三维的,其高点在中心,向各个方向辐射,有些象从五月柱上散出的彩带。
Our present existence on earth is three dimensional 我们如今在地球上的存在是三维的。
