Modelling of Creep and Stress Relaxation Test of a Polypropylene Microfibre by Using Fraction-Exponential Kernel

Figure 2

(a) Experimental creep curve (dashed orange curve) and analytical creep curve according to (8) (solid red curve). Experimental stress relaxation curve (dashed cyan curve) and analytical stress relaxation curve according to (14) (dashed blue curve) both scaled by 1/2000. (b) Relative error between experimental data on creep and relaxation and their model given by (8) and (14).
