Strain Recovery Optimization via Empirical Models

Since the interest is on strain recovery of the composite at high compressive strain, the empirical models to validate the effect of SDS are plotted as shown in Fig. 5.13 at

The optimized empirical model is validated with two sets of five sample blocks of 10-50 wt% gelatin mass fraction (four specimens from each block) with 0.56 wt% SDS loaded to 45 % compressive strain prepared via FM method and FD method respectively. The results are then compared with the optimized empirical model for consistency as shown in Fig. 5.15. The trends of the experimental results although 

Lastly, the contribution of air pockets or the lack of it could be another factor. The reduction of strain recovery corresponds to higher strength suggesting that there may be lesser air pockets in the FD specimens. The specimens fabricated by FM method and FD method showed little visual difference in terms of trend but the
