A new creep model for studying the non-linear viscoelastic behavior of cooked white, brown and germinated brown Thai jasmine rice by large deformation testing

A new creep model with three parameters for non-linear viscoelastic behavior is proposed as εt=ε0(1+tnk1+k2tn), where the applied stress is constant, εt is the strain at retardation time (t), ε0 is the initial strain and k1, k2 and n are constants. The relationship has been proved using data derived...
