Strength and deformation of rigid polymers: the stress-strain curve in amorphous PMMA
Poly(methyl methacrylate) (PMMA) is used to model the relaxation and plastic flow mechanisms of deformation, and the characteristic stress-strain response, relating it to its structure as much as it is known. The scope of this work is to identify and quantify the micromechanisms and the corresponding stress-strain relationships, and to assemble these into a coherent and self-consistent model for the observed mechanical behaviour. Detailed relationship between relaxation strength and time...[Show more]
