history parameter and two additional material parameters, i.e. G0 ref and γ 0.7. G0 is the small-strain shear modulus and γ0.7 is the strain level at which the shear modulus has reduced to 70% of the small-strain shear modulus. The advanced features of the HSsmall model are most apparent in working load conditions. Here, the model gives
