This paper proposes elastic-plastic constitutive relations for a composite material with two phases-inclusion and matrix phases-using a homogenization scheme. A thermodynamic framework is employed to develop non-local plasticity constitutive relations, which are specifically represented in terms of ...

보편적인 복합재에는 어떤 것이 있는가? | 구조체의 경량화 및 고성능화를 위해 입자 강화 복합재에 대한 적용 폭이 증가하고 있으며 이에 따라 복합재에 대한 현실적인 해석이 요구되고 있다. 보편적인 복합재로는 CC(Ceramic- Ceramic), MMC(Metal Matrix Composite), FRP(Fiber Reinforced Plastic) 등이 포함되며 또한 바인더 메트릭스(Matrix)와 금속 입자로 구성된 고체 로켓 추진제도 입자 강화 복합재의 대표적인 형태이다. | |
복합재 물성에 대한 균질화가 요구되는 이유는? | 한편 보편적인 복합재는 상대적으로 연성을 갖는 메트릭스(matrix)와 강성을 증가시키기 위한 게재물(inclusion)로 이뤄진다.(6) 이에 따라 복합재 물성에 대한 균질화(homogenization scheme)가 요구되며 대체적으로 Mori-Tanaka,(1,7∼9) Self- consistent(13∼15)에 따른 Hashin-Shtrikman(10∼12) 균질화 기법 등이 일반적으로 적용되고 있다. | |
