The compressive engineering stress (σ E )-strain ( E ) relationship up to rupture of several mannuronic and guluronic alginate gels was studied by varying the alginate effective concentration (c eff ) from 0.8 to 1.7% w/w and was correlated by using the power model (σ E =k nE ) with coefficients of determination (r 2 ) greater than 0.95...
