摘要
本文用Eshelby微力学理论分析,得到短纤维增强材料(SFRC)和基体材料两者的粘弹性本构方程之间存在简单的正比关系。发现体积含量为f的短纤维无序取向SFRC一维力学行为,等效于体积含量为F的短纤维单轴取向SFRC在取向轴上的力学行为。
According to Eshelby' s theory, a constitutive relation has been obtained for the short fiber reinforced composite (SFRC) with a considerable simple form. An equivalent fiber volume fraction F in isotropic SFRC has been discovered. One dimensional mechanical behavior of isotropic SFRC with fiber volume fraction f is equal to axial mechanical behavior of unidirec-tionally aligned short fiber composite with fiber volume fraction F.
