It is easily to form crack initiation in the interface between substrate and cladding layer, for the amplitude of tension stress is larger in Z direction.

Z方向的拉應(yīng)力幅值較大，易在熔覆層與基體的界面處形成裂紋源；X方向的拉應(yīng)力遠(yuǎn)大于Y方向的拉應(yīng)力，使裂紋大多垂直于掃描方向。

In the constant load and live load under the action of shear pin, and the circumferential weld will withstand high amplitude of cyclic stress, the strength and fatigue problem should cause height to take seriously.

在恒載和活載的作用下，剪力銷以及其周邊焊縫將承受幅值較高的應(yīng)力循環(huán)，其強(qiáng)度和疲勞問題應(yīng)引起高度重視。

The failure pattern of rock specimen subjected to dynamic loading is similar to that under static loading when the amplitude of stress wave is relatively low.

數(shù)值模擬表明：應(yīng)力峰值較小時，試樣的破裂模式與靜態(tài)載荷作用下的破裂模式相似；

Furthermore, under the same loading waveform the crack initiation life increases as the amplitude of applied stress decreases.

而且，降低正弦波加載時的應(yīng)力幅值可大大提高夾雜物/基體界面疲勞裂紋的萌生壽命。

The amplitude of crack-tip stress field decreases when the coefficient of hardening becomes bigger, and increases when viscosity increases.

裂尖場應(yīng)力和塑性應(yīng)變幅值隨材料硬化增強(qiáng)而減小，隨粘性增強(qiáng)而增大。

For soils with double-drainage boundaries, the amplitude of stress near the surfaces is greater and lag time is less.

對于雙面排水地基，靠近土層上下表面處應(yīng)力振蕩幅值較大，滯后時間較小；

The parameter has a significant effect on the amplitude of hoop stress.

飽和土參數(shù)對土體應(yīng)力的幅值有明顯的影響；

With the same incident pulses, the amplitude of stress wave was attenuated seriously when it traveled through the rough fractal joint compared with the smooth plane joint. The deformation of a rough fractal joint was found to be larger than that of a smooth plane joint.

在相同入射波條件下，粗糙節(jié)理巖樣的應(yīng)力波衰減程度大于平直光滑節(jié)理巖樣的衰減程度，粗糙節(jié)理的實際變形大于平直節(jié)理的變形。

The velocity of the vehicles has a little influence on the stress and the deflection in pavement and subgrade but rather significantly on the amplitude of fluctuating stress and deflection;

車輛速度的增加使路基路面的應(yīng)力和彎沉有一定的減小，但是應(yīng)力和彎沉的波動幅度隨車速的增加而增大；
