刨花板界面结合强度的研究
Study on Interface Combination Intensity of Particleboard
-
摘要: 建立起微观力学模型,可对刨花板界面结合情况进行分析,由有限元法分离出剪应力和正应力,从而论证了界面的破坏是由剪应力所致,结合薄弱处在受拉刨花受力一端的胶层界面处。Abstract: A microcosmic mechanics model was established and used to describe interface combination status of particle board. Shearing stress and direct stress were separated by limited unit law analysis. It's demonstrated that the interface destruction was due to shearing stress and that the end of glue layer interface of pulled particle was the weak point of combination.
