非線性流變學(xué)：大振幅振蕩剪切（large amplitude oscillatory shear, LAOS）

1.      振蕩剪切流動

當(dāng)給樣品施加正弦的應(yīng)變或應(yīng)力時，所產(chǎn)生的流動稱為振蕩剪切流動，流動由所施加應(yīng)變或應(yīng)力的幅度和頻率控制。所施加應(yīng)變幅度很小時，樣品產(chǎn)生的應(yīng)力響應(yīng)是有相位角的正弦信號；當(dāng)施加應(yīng)變幅度增加時，應(yīng)力響應(yīng)逐漸偏離正弦波。隨著應(yīng)變幅度的增加，應(yīng)力-應(yīng)變、應(yīng)力-應(yīng)變速率曲線（Lissajous曲線）逐漸偏離橢圓。

2.      傅里葉變換流變學(xué)

解析振蕩剪切行為最直接的方法是利用傅里葉變換，將時間域的信號轉(zhuǎn)換到頻率域，由倍頻信號的強度判斷偏離正弦信號的程度[1]。由于對稱性，剪切應(yīng)力應(yīng)該只出現(xiàn)奇數(shù)倍頻，而法向應(yīng)力差只出現(xiàn)偶數(shù)倍頻[3-4]。利用基頻信號定義的是應(yīng)變趨于零時的線性黏彈性函數(shù)（對應(yīng)于小振幅振蕩剪切SAOS），類似的可以定義高階倍頻下的特征模量[11]，最常用的是三階倍頻特征函數(shù)（對應(yīng)于中等振幅振蕩剪切MAOS）。傅里葉變換流變學(xué)的缺點在于高階倍頻下的特征函數(shù)缺乏明確的物理意義。大量的研究表明，MAOS和LAOS特征函數(shù)能夠比SAOS特征函數(shù)更敏感的表示出材料結(jié)構(gòu)的細(xì)微差別[6,7,8]。

3.      幾何平均分析

另一種解析LAOS行為的方法是幾何平均方法[5]，即通過閉合應(yīng)力-應(yīng)變曲線對應(yīng)力或應(yīng)變?nèi)∷阈g(shù)平均，得到平均應(yīng)力-應(yīng)變曲線和應(yīng)力-平均應(yīng)變曲線；對應(yīng)力-應(yīng)變速率曲線可得到類似的平均曲線。幾何平均曲線在特定條件下可以通過Chebyshev多項式建立與傅里葉變換流變學(xué)的關(guān)系[2]。幾何平均方法不依賴于LAOS的實驗方法（控制應(yīng)變或控制應(yīng)力），特別適合復(fù)雜流體（如屈服應(yīng)力流體）屈服轉(zhuǎn)變[10]、壁面滑移[9]等方面研究。
