A good agreement has been found between the experimental and numerical results of Glass/ Hemp
The experimental and simulation result of tensile tests of the different specimen has been displayed, as shown in Fig. 4. The simulation results have been calculated based on the input mechanical properties of the different fibers, which are listed in Table 1. Figure 4 shows the tensile load versus displacement curve. It is clear that…
A joint-year is defined by a history of smoking one joint per day times the number of years smoked
Natural fibers are semi-crystalline materials composed generally of an amorphous part basically consisting of the macromolecules of lignin and hemicellulose and a crystalline portion of cellulose.
