dislocation n. 1.【醫(yī)學(xué)】脫位,脫臼;離位,轉(zhuǎn)位,位移。 2.【地質(zhì)學(xué);地理學(xué)】斷層,斷錯;【物理學(xué)】位錯。 3.混亂,打亂。 a disastrous economic dislocation 災(zāi)難性的經(jīng)濟混亂。
However , the small - size particle - reinforced composite is more prone to deformation localization than the large - particle composite under impact loading . dislocation models considering the effects of reinforcing particles are used to determine c1 , c2 and c3 related to effective strain gradient in the present work . based on taylor relation and the kinetics of dislocation multiplication , glide and annihilation , a strain gradient - dependent constitutive equation of mmcp is developed 發(fā)展了具有顆粒增強金屬基復(fù)合材料材料背景的三個位錯模型,結(jié)合顆粒增強金屬基復(fù)合材料代表元模型標(biāo)定了這類復(fù)合材料變形中的等效應(yīng)變梯度,并用這些結(jié)果成功地表征了這類復(fù)合材料變形強化和局部化中的增強顆粒尺寸依賴效應(yīng)。
