Characterizing the stress relaxation behavior of unidirectional prepreg through a parallel fractional-order viscoelastic model

In the hot-stamp molding and hot diaphragm forming processes of composites, pressure significantly influences shaping quality. This study establishes a novel parallel fractional-order viscoelastic (PFOV) model with two Scott-Blair elements, achieving remarkable accuracy (R ^2 = 0.99) with fewer para...
