The main contributions of the dissertation are as follows : on the basis of experimental results, the operational effects, such as the magnitude of magnetic field, the temperature and the rate of shear strain, on the shear stress of the mr fluid are shown and models of the quasi - bingham model and a nonlinear model for the shear stress of the mr fluid also are developed, in which the characteristic of " shear - thin " of the mr fluid is described
論文的主要貢獻如下：通過測試磁流變液剪切應力與磁感強度、剪切應變速率、溫度的變化規律，建立了能反映磁流變液剪切變稀現象的剪切應力與剪切應變速率的磁流變液模型。根據磁流變液模型，從理論上建立了能在較寬的電壓內范圍比較準確地預報磁流變阻尼器輸出力的近似公式。 -

The strain rate sensitivity would be increased with the increase of volume fraction of sic particles. the damage mechanism of sipc / al composites was dominated by the shear cracking of sic particles along the direction that was vertical to the loading
同時該復合材料存在應變率敏感性， sic含量的增加導致復合材料應變率敏感性的增加，以垂直於載荷方向的增強西安理工大學碩士學位論文相顆粒的剪切開裂為主要破壞模式。 -
Abstract : a previously proposed approximate quasi - static theoretical method is employed herein to examine the deformation and perforation of a simply - supported circular plate struck by a flat - faced projectile at normal incidence. based on the principle of virtual work, static load - displacement relationships are first obtained and then used to predict the energy - absorbing capacity of the plate subjected to relatively low speed impact. it is shown that good agreement is obtained between the theoretical predictions and the available experimental data, provided that adiabatic shear plugging failure does not occur, but the influence of strain rate sensitivity is taken into account
文摘:採用準靜態近似理論方法分析簡支圓板在平頭彈丸正撞下的變形和穿透.首先基於虛功原理得到了靜態荷載位移關系，並將其用於預測低速沖擊下圓板的能量吸收能力.當考慮了材料的應變率敏感性，並且不發生絕熱剪切沖塞破壞的前提下，理論預測和實驗結果吻合良好
