of the CNTs and compression strains within the matrix. Stage-II persists until the yield point of the composite‚ beyond which both aluminum and the nanotubes undergo plastic deformation. It is stage-III and it features delamination of the Al-CNT interphase. Therefore‚ unloading of the composite will demonstrate permanent deformation attributing plastic strains of the matrix (εpm) and the reinforcement (εpr); Et=Epm+Epr (4) Finally at stage-IV‚ crack initiation a growth occurs‚ which continues

Biology Notes 1. Organisms are made of cells that have similar structural characteristics. 1 Outline the historical development of the cell theory‚ in particular the contributions of Robert Hooke and Robert Brown. The development of the cell theory starts in the 1600ʼs with Robert Hookeʼs discovery of cells when viewing a piece of cork under a microscope and describing them as a nun house. Anton van Leeuwenhoek was crucial in the development of microscopes making simple microscopes through advanced
