The matrix is assumed to be an elasto-plastic material that deforms according to J2 flow theory.
The stress distributions are obtained numerically and compared with a different shear-lag model that employs total strain theory as a constitutive equation of the matrix material.
Introduction It is well known that prediction of the mechanical properties of fiber-reinforced plastics (FRP) requires an detailed understanding of the stress states in the constituent materials.

In order to prepare fractal carbon films, iron nitrate was employed as catalyst precursor, copper plate as substrate, and ethanol as carbon source materials.
In our experiments, iron nitrate was employed as catalyst precursor, copper plate as substrate, and ethanol as carbon source materials.
Raman spectroscopy was usually employed to characterize the graphitization of carbon materials.
It has a high sensitivity to the disordered structures in carbon materials. 1550-1600 cm-1 is the graphite band (G-band) which is produced from the high degree of symmetry and order of carbon materials, and generally used to identify well-ordered CNTs [13].
